we had sex about 1 month ago and she hasnt had her period which is usualy at the beginning of the month, it was our fisrt time so im thinking it could be due to the body getting out of course due to being the 1st time, i used condom but they cant always be trusted. (didnt have sex during her period)...and she dont wanna take a pregnancy test so......whats happening here?....THANKS!!!Calm down, she may NOT be pregnant.. I hate when people make a diagnosis without one day of medical school. Yes, it is possible that she is pregnant. However, it is also very very common for harmonal changes to take effect after a girl loses her virginity... I would still encourage her to take a pregnancy test. But don't fret she may not be pregnant.she might be pregnantWell, if your girlfriend has pretty regular periods, she could very well be pregnant. However, this can also be due to many different things such a weight loss, weight gain, stress, diet, medications, and other factors. The best way to find out, is to take a pregnancy test. Tell her to do it first thing in the morning, when her urine has the strongest level of the pregnancy hormone. You both need to know, so you can take the necessary steps...It could be pregnancy (you don't generally get pregnant during her period, as this is when the uterine lining is shedding). It could also be stress, hormone changes, sickness, any number of things. Taking a pregnancy test would definitely be a good idea to rule that out and if it's not that, then just wait it out and see if ti comes back.
