I'm not sure if I'm on my period but the way I'm bleeding seems to be it, my sugar pill week actually starts this sunday and i started bleeding/spotting monday. I'm not sure if I synced with my friend because I stayed with her for 4 days and she's on birth control also, so i'm not sure if that's possible? I haven't had sex for 3 weeks and I started bleeding the day after i had sex so i'm also not sure if that's the cause but I've been bleeding for about 4 days. I'm not sure what's going on??? Am I pregnant? I'm very bloated.
