I am 19 years old and I have recently moved in with my boyfriend. We have a very active sex life and, well, a couple days ago we had anal sex... and ever since then, I haven't really hard to use the restroom, but I also haven't been eating the healthiest of foods. Yesterday, all I ate was cheetos and a lunchable, and the day before that, I do believe I had two meals, both fast food, and I know I ate the day before that, too, and I still haven't had to go, which is unusual for me. When I do go, it's a VERY little bit, usually having red blood and a bit of mucous in it. I have no idea if the sex has anything to do with it, but I don't think that would still be causing the blood/mucous 4 days later. I'm pretty scared, and worried that something might be wrong. I'm worried about eating, because I'm worried about some sort of blockage or something. What does this sound like??
