Myself and my partner have been trying for a baby for a few months now and i have been using the LH predictor sticks which have been positive for 8 days now also for 3 days now i have been getting slight cramp like pains in my stomach..I feel really bloated and have stinging shooting pains on boths side of my stomach...they come and go. My cycles are long they vary from 30 to 34/35 days....it's 31 days since my last period. I done a pregnancy test today(day 31) and it's negative. any idea what's going on?
