Hi, I am 32 years old.. Have been trying to conceive for nearly 2 and a half years. Recently saw a doctor and got fertility pills for a more regular menstrual cycle. Took the pills for 5 months and my menses was regular. Stopped in Jan and in feb my menses was still regular at 27 to 29 days. This month, it is already my 33rd day and no period. But lower back is hurting. Tested on the 31st day but it was negative. Is it normal to get a negative? Trying so hard but its disappointing..
