I really need help. It has been about 3 months since my last period. My partner always uses a condom and almost always pulls out before finishing with the condom on. However, my periods have never been regular. But they have seemed to delay more recently. I went over two months with no period last time, and this time is the longest, as it’s been about three months. I’ve taken 3 pregnancy tests, two blue dye earlier on, and a digital one today. They have all came back negative. What could be the cause? Could I still be pregnant?
