Hello, Recently I've Been A Lot Of Changes With My

Hello, recently I've been a lot of changes with my body. The first change was when i started spotting, which was very faint (pinkish discharge) for 2 days and the third day it was red. It stopped after that. (Im on birth control for the 2nd week, and i shouldnt have a period now) Today i used the restroom to notice that my vagina is very warm, as if it was steaming. Not to mention i havent been able to have a about bowel movement in 4 days, just gas which is extremely frustrating. Could you help me?
