Can being pregnant cause you to go to the bathroom alot?

My husband and I have been having unprotected sex and I am concerned I might be pregnant. I have been breaking out, feeling really nauseated (but I am not throwing up) my boobs hurt specially when I try to lay on them, I had a weird pink discharge one time when I peed a few nights ago and...umm I have been going number 2 alot. Also I think I have hemorrhoids but I think its because I go to the restroom alot. Is that a sign of pregnancy going number 2 alot? I feel really weird asking this but I have been going alot and I do not eat any more than I did 3 weeks ago when it started. thanks=0)
