I started my period on July 25th for about 5 days and have been sexually active with my fiance since then. The week of August 20th I had really bad cramping, lower back and side pains, upset stomach/bad indigestion, and was extremely hungry which I've never experienced before. I was supposed to get my period on August 22nd (I usually have a 28 day cycle) and took 3 pregnancy tests (a bit obsessive I realize now haha) and all 3 were negative. However, I did start to have a little medium bleeding on the 25th with it being very light yesterday and today (which isn't usually normal for me) with the same symptons from last week still being persistant...is there a chance I could still be pregnant and miss my next period? All advice anyone could give me would be greatly appreciated!! Thanks.
