Hi, last week I took two home pregnancy tests that came back negative. I went to the doctors just incase as I have sore breasts, blood like taste in my mouth, swollen lower abdomen that appears to swell up when I eat, slight diarreah, and sometimes nauseous. The blood test result (conducted Wednesday this week) came back negative so I took a further home pregnancy test which also came back negative. I continued to check the test during the night and it remained negative until I checked it again at the end of the next day (Thursday) and the test appeared positive. I have recently had a break up with my partner and am not sure if I am mixing emotion with these symptoms. Please help!
