I had a tubal ligation done 6 years ago, and am missing period. I also feel very pregnant! My last period was around July 6 and was very light. I have always run like clockwork and have never missed a period unless I was pregnant. I am 35 and have 3 children. All of them I tested positive at around 2 1/2 months. I also had light periods in the beginning with all of them also. Symptoms include, missed period, lots of discharge about a week ago, light light brown blood once when I went to the bathroom a couple days ago, headache for the last 6 days, total nausesness, constipation, and sensitive smell and crying at the drop of the hat. I also usually feel myself ovulate every month and it kills me, but didn't feel that in July either. No pain, no real blood. Kind of run down and have some colostrum coming from both nipples. I have also tested negative on 5 tests?? Should I just wait and test again next week?
