okay, so i got a depo shot when my baby was born Feb 3,2011. then for those 3 months i had a heavy period, i went to the er they found nothing, asked me to give it a few more days. one more month and the bleeding stop. my RN asked if ii was still was going to stay on depo? i said no, last month i had a normal menstrual cycle. now, it's been 30 days with out a cycle. can i be pregnant? it's been like about 6months from my last and only shot, also not on birth controls, all we been doing is pulling out.
