My cycle is usually 29-31 days. Today is day 37 and no period. I have never been this late before. I usually have very sore boobs about 10 days before my period but my boobs are fine now, don't hurt at all which is deff not normal. ive taken 3 hpt and they are all negative. Last night i couldn't sleep but i felt very tired and i get nauseous from time to time. I havent been any more stressed than usual and i keep having cramps like i have just started but no bleeding at all. Someone please help!! Its not normal that my breasts do not hurt this has never happened before.
