I had unprotected sex a few days ago but i am not ovulating and my period sometimes is off by a few days i am not expecting my period till january but i have a lot of cramping recently, could it be possible that i am pregnant ?

Hard to guess...: It can be hard to tell if a woman is pregnant because some of the symptoms seen in early pregnancy can also happen in non-pregnant women. A urine pregnancy test gives a reliable result if done correctly. One can test about 3 weeks after sex (3 weeks after when conception might have occurred), or 1 week after missing a period. An Ob-Gyn doctor can evaluate any persistent or worrisome symptoms.
