A common question asked amongst women who are trying to conceive (TTC) is "how long after coming off birth control (the pill) does it take for my cycle to regulate itself?"
The problem with that question is it varies from woman to woman, so no one answer can apply to everyone. A few things that should be considered when asking how long it will take for your cycle to regulate, is how long you were on the pill for. There does seem to be a common trend amongst women - those who have been on the pill for years will probably regulate at a slower rate than those who only used it for weeks or a few months. Another point to consider is how long after you come off the pill does the hormone start leaving your body. With the pill, it stays in your system for much longer than other contraception does (i.e. the implanon will be out of your system within 72 hours whereas it will take at least a couple of months for the hormones the pill produces to be out of your system).
It's not uncommon for women's cycles to be all over the place after coming off the pill and it's also normal not have a period for months (which can be frustrating if you want to chart your cycle because you are TTC).
Some women are lucky and they will have a period within just a few days or weeks and their cycle will regulate itself in record time, but once again, there are several things that affect how long it will take for your cycle to regulate.
With the pill, patience is required. You probably won't get pregnant soon after coming off it. Expect to wait at least a couple of months, but it usually does take longer that a couple of months for everything to return back to normal. Don't be disheartened - just find the strength to wait it out.
