Ok, my period is 12 days away but I had some cramping last week and a few spots of blood when I wiped a few days. The last 2 days my nipples have hurt. Not sore, but hurt incredibly bad. I can't even have a bra touch them. They've never done that even on my period before. How soon after your breast pain started were you able to get a BFP? It's our first month TTC but my mom was fertile Myrtle and she said this type of pain is what alerted her with both her pregnancies.
