You can basically experience any withdrawal or side effect for up to 12 months. Every persons experience is entirely different, some don’t notice a thing and get a cycle right away, for some it’s irregular, and for some it doesn’t even occur for months. It’s best to go in without any expectations but if you decide to quit it should at least be for 12 months, else you’ll risk an increased risk of clots. So be sure it is something you’ll commit to long term. Don’t expect your bleeds to be the same as when you were a young teenager, as it’ll likely be very different now you’re entering adulthood. Things change!
