Okay so, me and my boyfriend had sex on 2/14, he pulled out so he didn't cum inside me. I'm supposed to start my period on the 24th (always, never late never early) i started my "period" today 2/17 but it's not heavy like it always is, its like a pinkish colour and it didn't fill my pad either. the only time it seems redish is when i wipe myself. could i be pregnant.? i am 16 and I'm freaking out, I'm not ready for a kid, so if somebody can give me some advice i would really appropriate it. thanks
