Well i would just like to say that AF cramps can mimic BFP signs and symptoms, i guess its what knowing is the norm for you. I never paid attention in detail to signs and symptoms i get after ovulation and right b4 AF, i charted my symptoms for 3 months and around 5dpo i get cramps, twinges,bach ache, sore boobs making me think wow a big fat positive, but for me, it means nothing.
