My boyfriend and I had sex and we used a condom. We were grinding before anything but were fully clothed in the process (I didn’t ejaculate then). we made sure the condom was on correctly before there was any genital contact between his penis and my vagina. It didn’t end in him ejaculating and he kept the condom on until he got to the washroom where he removed the condom and filled it with water to check for rips or tears, which there were none. I got my period the week after so I would think pregnancy did not happen. Did we use a condom correctly and is there a chance of pregnancy?
