Hi, I am a 19 year old female.. I have been sexually active but the guy I was with def used a condom . But I am late on my period I have taken several pregnancy tests and my nipples have been fairly sore.. I've been stressing a lot to is that why I'm late ? Someone help !

And the pregnancy tests all came back negavtive

How late are you, if you are not at least a week late, just wait.

If a week late, then are you testing early in the morning, with the very first urine of the day.

Condoms have about a 3 to 10 percent failure rate.
