Last month I took plan b the day I was supposed to get my period and 2 days later I got my period (or maybe just bleeding from the pill??) and then right after the bleeding stopped I put my birth control in. Use condoms AND birth control. My period is supposed to come tomorrow. I've been having slight cramps for about 2 weeks, no swollen breasts, but since 2 days ago just my nipples started hurting. Am I just over thinking that I'm pregnant? I'mavoiding pregnancy I have a 4 month old and can't afford another
