Okay so I've just had my period and came off it about four days ago and everyday after my period I've had sex with my boyfriend without protection and all of a sudden my pee had this strong smell and I was kinda like what but I had not itching or pains so it wasn't a urine infection and I don't have pains in my sides so it's not a kidney infection I don't think but when I just wiped there was this very light pink discharge on my toilet paper what could it be ? Other websites say it could be pregnancy but I'm not sure ?
