Idk what it is

On Saturday I had sex with my boyfriend. 2 of our condoms broke but the third didn't. Also he never came in me. I noticed while taking a shower that there was a smell down there but I didn't think anything of it. I washed myself like normal and drank more water. My urine cleared up but the smell didn't. I got my period Monday and the blood even had the smell. I don't know what it is. Please help.
