Hi. I'm confused about my symptoms and was hoping someone could help me. I am taking birth control pills, and have been for a year now. About six months ago, I had unprotected sex with my boyfriend using the pull out method. After that, my periods became lighter, and are still that way today. They are heavy for three days now, and light for 2, when they used to be heavy for four days, and light for one. Also, I feel like I have to use the restroom more frequently than usual. My breasts have grown a cup size, but were never sore. They are also veiny now. I have gained a few pounds, but probably just around 5, and am a freshman in college this year. I have never missed a period, and have taken probably 7 home pregnancy tests. Also, I have had two ultrasounds that came back clear, & i was given a pregnancy test after each ultrasound that came back negative. But, when I lay down I can feel and move something hard in my stomach that I never noticed before. I don't know if I should be worried or not, but I think about this often. I'm not showing a pregnant belly bump, but I can see that my belly has a bit of a pouch now, even though it might be from weight gain. I would be around 23 weeks pregnant I think? What should I do?
