After my abortion, the first cycle was a bit heavier and longer than normal. After it stopped, I started a new pill pack and within two to three months I was having more regular (with regards to heaviness) cycles consistent with the time of the month for my pill pack. So, for a little while, they may be heavier and you may start at a different time.
A few months ago, we had a condom mishap and although I am on the pill, we weren't going to take any chances so I obtained ec through the local planned parenthood and that made me start a few days earlier. I went back to my regular cycle when I started the new pill pack. I haven't had any long term effects from the abortion or the ec.
I hope this helps and thank you, thank you, thank you for everything else you have said on here.
Peace,
