Lately I've been feeling sharp pains in my lower left abdominal area:/ my boyfriend and I have had sex around my ovulation date and I was due for my period 15 days ago and I still no period. Am I haveing a ectopic pregnancy? Also I frequently have to urinate, I'm really hungry and VERY fatigue. Ooh and it feels like my Fallopian tube on the left is in pain:/ like a lot! I'm also on implanon birth control implant
