Ok, my girlfriend got the depo shot for the first time about a few days after valentine's day. We followed the rules on no unprotected sex for 2 weeks. We even waited 3 days after we were able to before unprotected sex, and i didnt even really cum in her week after. *Yes i know 1 sperm can cause it all* anyways. She has been running late on all her periods before this *between her periods its about 5 weeks* we never worried about because of stress relatied issues. Now its the period after the depo and she had some dark, dark red fluid coming from her, so she thought she was on her period. well after she thought she had stopped, it started again but the color *she says is normal* She had some friends that said that they had misscarriages and were on their periods for 2 weeks. Anyone know??
