I've always had irregular periods, and went on Birth Control for about 10 years. I went off BC in January, had surgery to remove a cyst off my right ovary in June and was having regular monthly periods again. It's been probably 7 weeks since my last period, but the 2 pregnancy tests I took last week were negative. Does anyone think there could be a chance I'm pregnant and getting a false reading? Or is it more like that my body is just becoming irregular again? Just looking for some advice from any ladies who have had similar situations... Thanks!
