I have not had my period in 6 weeks and 1 day. I have taken tests, but not in the morning when I first wake up. My period is never late. Yes, me and my boyfriend have unprotected sex. The only symptoms I am having is sore nipples (which I never get before a period), moodiness, extreeme fatigue, lower back pain, and slight weight gain. I have been told by many people to go to the doctor. But I really want to wait until october to see if my period is going to come down. Since myperiod is very dependable, I doubt it will come. So how come my pg tests are coming up neg?!?!? The veins in my breasts and nipples are starting to show more than normal. I am on the verge of beicoming very aggravated with all of this and ust say f it!! whats the deal!?!?!?!?! Help!!!!!!
