What Is Mirena?
Before we tell you anything else, you must know what Mirena is and how it works.
Mirena is a T-shaped intrauterine device that contains levonorgestrel hormone, works as a contraceptive, and helps treat heavy periods. It works by thickening the mucus in the cervix, which, in turn, stops the egg and sperm fertilization, hence preventing pregnancy.
To treat heavy menstrual bleeding, it works by thinning the lining of the uterus, lowering blood flow.
In every menstrual cycle, your body prepares itself for a possible pregnancy. Therefore, endometrium forms- a tissue that protects the baby. When there is too much endometrial growth, eventually, you end up getting heavy periods.
With Minera, there is thinning in endometrial growth. Therefore you get light periods compared to those you used to get. Women complaining of heavy periods can get Mirena inserted.
Since Mirena thins the uterus lining, it can lead to light or no periods. Therefore, you can also have a complaint about Mirena late period.
What Causes Mirena Late Periods?
Mirena releases levonorgestrel- progestin, a synthetic progesterone hormone. Progesterone hormone helps regulate the menstrual cycle and helps maintain the early stages of pregnancy.
We know how painful it is to wait for periods. You may have all the symptoms of it, such as cramps, bloating, and breast tenderness. But you can not see the red drop of blood to confirm that you have got periods.
Naturally, your body may take some time to get set on a new contraceptive and get adapted to it. Your periods may be irregular in a new contraceptive method. Or sometimes, you may not even get them for a long time. For that, you do not need to panic. However, consulting a healthcare provider is always a good idea.
If you ever miss a period, with or without contraception, you must consult with a healthcare provider about it. They will rule out the underlying cause for it.
While you have a Mirena intrauterine device implanted, it can cause late periods because of the reasons such as:
By Thinning The Endometrium
The tissue of your uterus- the endometrium, provides support to the uterus to sustain a pregnancy. However, when that does not happen, it sheds itself as periods or blood. Mirena works by thinning the endometrium so that your body can not hold the pregnancy. Therefore it can cause late or missed periods.
A con of it can be that it causes your periods to get late. It happens because the endometrium becomes so thin that there is no such tissue to bleed.
Apart from Mirena itself, your periods can get late because of various other reasons, such as:
Mirena late period can occur due to stress. Normally, your hypothalamus- an endocrine gland in your brain regulates your periods. It does that by signalling the pituitary gland, which in turn signals the ovaries to produce estrogen and progesterone hormones.
Estrogen and progesterone hormones regulate the menstrual cycle and pregnancy. Any abnormality in their levels can affect your fertility and menstrual cycle.
When you are stressed, your body produces a hormone called cortisol- also known as the stress hormone. It affects your periods, causing them to get missed, light, or even a total loss.
You might have a complaint about late periods with or without hormonal contraceptives due to stress. If this is the reason, you must practice stress-relieving tips.
If you cannot get rid of stress on your own, you must visit a psychologist. They can help you cope with stress so that your periods can regularize.
When your periods get late because of stress, you may have other symptoms too that indicate that stress is the underlying cause.
Chronic stress can also lead to weight loss or sudden illness, which can, in turn, affect your menstrual cycle.
Low Body Weight
Women having eating disorders often have a complaint of late or missed periods. It happens because they have low body fat. Estrogen and progesterone are the hormones that regulate the menstrual cycle.
The fat cells in your body produce estrogen. Therefore, when you do not have fatty tissues in your body, the estrogen levels eventually fall, which, in turn, can cause a loss of periods or getting them late.
Having a 10% low body weight according to your required body mass index can cause a stop in ovulation. Therefore, periods do not occur.
If you get your periods late due to low body weight, your healthcare providers will advise you to gain weight. However, make sure you do that healthily. It is never good to consume too much sugar and bad fats to gain weight.
You can gain weight healthily by eating plenty of fruits combined with dry fruits such as cashews, nuts, and almonds. Drinking two cups of milk in a day is also a good idea.
Do not take your complaint of late periods lightly, as it can affect fertility, which is eventually much more important than your beautiful figure.
If your periods are late because of being underweight, they will get regularized when you gain enough weight for your reproductive system to function well.
Obesity Or Overweight
Being obese or overweight can also affect your menstrual cycle. It happens because we have told you earlier that fat cells produce estrogen hormones that regulate periods. When there is too much estrogen in your body, you may get late periods or no periods.
If your periods are late because of being overweight or obese, your healthcare providers will advise you to lose weight. And once you shed those extra pounds, your periods will also get regular.
Chronic diseases can also disrupt your periods. It often happens when your body can not absorb the nutrients.
Your periods can get late or missed if you have celiac disease. It happens because your body can not absorb the nutrients. Due to this, it does not get enough calories you need to maintain your weight or carry out normal bodily functions.
When your body does not meet the caloric requirement, your periods get disrupted because no ovulation occurs. Your body does not release an egg to prevent pregnancy. It perceives that your body can not bear the load of the baby and can not meet its dietary requirement. Therefore, when there is no ovulation, no periods occur.
Your periods can also get disrupted with diabetes and chronic kidney disease, and other conditions in which you lose too much weight rapidly.
Mirena’s late period can also happen because of early peri-menopause.
Women undergo peri-menopause at the age of around 45- at this stage, you have symptoms of menopause with irregular or late periods.
In some women, peri-menopause may start earlier, around the age of 40. It shows that your egg supply is winding down, but still, there are some eggs.
At this stage, you need to have proper contraception too. Therefore, Mirena is needed, but your periods can get later.
If you do not get periods for more than three months, you must consult with a healthcare provider. Sometimes it may be a symptom of some underlying health condition. Do not always misconstrue missed or late periods in your 40s with peri-menopause.
In your neck, there is an endocrine gland known as the thyroid gland that produces thyroid hormones, regulating various bodily functions.
Sometimes, your thyroid gland may not function well, and the production of hormones is affected.
If your thyroid gland produces too much thyroid hormone, the condition is called hyperthyroidism and when it produces too little thyroid hormone, the condition is called hypothyroidism.
Hyperthyroidism and hypothyroidism can cause Mirena late periods. Sometimes they can also cause amenorrhea- loss of periods for over three months.
To regularize late or missed periods due to thyroid dysfunction, your healthcare providers will prescribe medications to treat thyroid issues.
When your thyroid hormones are at optimal levels in your body, your periods normalize.
The most common reason for missed or late periods is pregnancy. It is the first thing that comes to your mind if you are sexually active.
Many women think they are on contraceptives and can not get pregnant. But this is not the case.
Contraceptives can fail, leading to an unplanned pregnancy. Therefore, no matter how effective your contraceptive method is, it can fail to prevent pregnancy. However, that happens rarely. But a chance is still there.
Mirena late period can also happen if you are pregnant. Therefore, you must take a pregnancy test soon if your period does not occur on time.
When Should You See A Doctor?
It may take some time for your periods to get set on a new contraceptive. However, if one does not suit you, your healthcare providers may change it.
Your body may react differently to various contraceptives. Therefore, the side effects are not the same for all.
If you have any of the following complaints with a new contraceptive, you must visit the healthcare provider:
- Nausea and vomiting
- Unexplained vaginal bleeding
- Heavy periods
- Bleeding after menopause
- Pain or discomfort in the lower body
