Me and my fiancé had sex around January 20th sometime and we used a condom but it broke and didn't realize it till after he finished. I'm not on birth control and I was suppose to get my period February 6 or 7 and I haven't gotten it yet. I am under a lot of stress right now so I'm not sure if it's just stress making me late or could possibly be pregnant.. I am not having any pregnancy symptoms other than just being late.. Any thoughts?
