So, other contraceptive methods should be used during this period. Or, one can abstain from having sex if other contraceptives are not preferable for her. Otherwise, there is a chance of pregnancy.

The 7 Day Rule In Particular Conditions

The rule applies similarly in different situations like,

After Abortion or Miscarriage

  • Implanon should be inserted within 5 days of 1st-trimester abortion or miscarriage
  • It should be inserted between 21 to 28 days following the 2nd-trimester loss of the fetus.
  • If the above recommendations are not followed, immediate contraception isn’t achieved. Then a barrier method of contraception is needed for 7 days after insertion.

Postpartum Conditions

  • For non-lactating mothers, it is inserted between 21 to 28 days postpartum.
  • For lactating mothers, it should not be inserted until the 4th postpartum week is over.
  • If these rules aren’t followed then a barrier contraceptive method is needed for 7 days after insertion.

Switching From Other Contraceptive Methods to Implanon

  • You might be switching it from combined hormonal contraceptives. In that case, it’s inserted on the day following the last active oral pill. Or, on the same day of removal of the vaginal ring or transdermal patch. It can also be inserted following the usual tablet-free or placebo tablet interval.
  • You might be switching it from progestin-only contraceptives. In that case, it is inserted on the day of the next due injection. Or, within 24 hours of taking the last minipill. Or, on the same day of removing the previous intrauterine contraceptive device (IUCD).
  • If one deviates from these guidelines then she must use barrier methods for the next 7 days.

What to Do If You Forgot to Follow the 7 Day Rule?

If you’ve already had unprotected sex within 7 days of insertion, take an emergency pill immediately. Still, if pregnancy occurs and you decide to continue it, you must remove the Implanon quickly. And if you decide to do an abortion, the Implanon can remain inside during the procedures. It can then continue its term of contraception as usual.

Now that you know everything about implanon 7-day rule, it’s time to gain some knowledge on the basics of it. It’s always safe to remain informed about the contraceptive that you are using.  

Implanon- a General Overview

It is hormonal and can be doubtful to a new person. But as you’ll get to know more, you’ll realize that there is almost nothing to worry about.

How to Use It?

  • You have to go to the physician twice to insert an Implanon. Firstly to consult about your overall state of health and get the prescription. And, secondly after collecting the Implanon from the pharmacy to implant it.
  • It is a soft, flexible, progestin-only implant of 4 cm length and 2 mm diameter. It is preloaded in a sterile applicator and injected subdermally from it. The insertion site is 2 inches above the elbow joint. And, in the inner side of the non-dominant arm. 
  • A trained person will place your non-dominant arm in the proper position. Then the inserting site will be marked. The mark along with its surrounding area will be sterilized. A local anesthetic like lidocaine will be injected along the mark and direction of implanting. The Implanon will then be injected carefully in the subdermal region and the applicator removed after completion. 
  • After implanting, it needs to be palpated by the specialist and also the patient. It is removed or exchanged with another Implanon after 3 years.

How Implanon Produces Contraception?

It is progestin-only and does not contain estrogen. It works mainly in 3 ways:

  • It thickens the cervical mucosa, so sperm can’t enter more inside for fertilization.
  • It decreases endometrial thickness and prevents a fertilized zygote from implantation. That is, it prevents pregnancy at this point.
  • It alters the motility of the fallopian tubes. As a result, it prevents the ovum and sperm from reaching each other.

It also has effects upon follicular development and ovulation in the ovaries.
