Hello everyone. I have been on birth control, but I recently got off of it. I was supposed to get my period on April 16th, but I still haven't gotten it. I had unprotected sex on April 19th, and I've been experiencing some symptoms. I was having a pale yellow discharge for 4 days, which stopped, and now I just have a lot of clear discharge. I need to urinate a lot more frequently than normal, I've been having cramping in my pelvis and lower abdomen, especially after eating; along with getting nauseous too. Also last night my breasts started to feel tender and full. I have taken 3 pregnancy tests over 3 days, the first one had a barely visible faint line, the second one also had a faint line, but was a little more noticeable, and the last pregnancy test I took had an even darker line. I am confused though because I got a blood test done at a lab after the first pregnancy test and it came back negative. Yet the urine tests keep getting darker. Does anyone know what could be going on?
