My expected ovulation day was the 18th, since the next day i have been urinating frequently, my nipples are sore to touch, when i stand up my eyes go funny like im going to pass out and also have had bad stomache pains/ cramps constantly since the day after ovulation. Yesterday i took a clear blue test and showed negative but i only checked the fist couple minuets. 20-30 minuets later i checked and and it showed a faint blue positive line (could that be a evap even though its blue?) today i have took a pink dye and is showing negative.. has anyone experienced this?
