Guys... I AM TERRIFIED. My period is a few days late... And my boyfriend and I have sex without condoms because he's allergic (and he hasn't bought the no latex ones yet). And the thought of being pregnant makes me shake and feel so sick... I'm having my normal period symptoms.. But no blood... A nurse I'm friends with said I looked like I needed iron (she didn't know about the period thing, she just brought it up) and I know that effects it.. But my period is NEVER late.. Can you just calm me down...?
