My girlfriend is almost a month late on her period, approximately 3.5 weeks. I took her virginity on New Years 1/1/14 and also had sex twice about a week later. She was supposed to get her period around the third week of January. And now were almost to the third week of february and still nothing. We used a condom all three times and i checked it after to make sure nothing was wrong, which nothing was. I also pulled out every time just to be safer. We are beginning to worry and Im just trying to find some answers as to why she is so late. She says she s been late before but never this late. She s also beginning to stress a lot more and I know that could even delay it longer so I m trying to just keep her calm. Could taking her virginity cause her to have this irregular cycle? Any information would be great, thank you.
