I am 9 days late. Possibly conceived a day after my fertile days. I have some symptoms of pregnancy, such as nausea, tender breasts, and fatigue. I have had really light cramping the past couple days in the front pelvic area. But through out last night and today I have had some stronger cramping in my lower back. I just used the restroom and there was bright red blood on the toilet paper, but not a lot. Could this be the start of a late period or could I be pregnant. I have taken 3 tests and they all have said negative. My period jumps all over the place and is never the same time of the month.
