I was on primoult for around a week and had protected sex during that period using condoms and also ensuring my partner ejaculates outside me after pulling out sufficient time before. I had stopped primoult on 22nd but i am not getting periods yet. However for the past few days i have been occasionally having mild period cramps like i used to have before periods actually start. So thats a sign that my periods ard coming or is it worrisome for a pregnancy ?
