My last depo shot was last March and it only lasts 3 months but after you stop taking them then it takes around a year for your periods to return to regular again. I can only remember having a period on Nov. 1st but then i had another one the same month. Then i had another one on Dec 25th. So I'm wondering if this means i wont have a period this month. Can anyone tell me that since i think my periods are just irregular becuz im worried that i might be pregnant because i might npt get my period but then again it might because my periods aren,t totally back to normal and i might not be releasing an egg. Oh and can anyone tell me if i don't get my period does that really mean i didn't release an egg because the period only happens when the uterine wall sheds.
