Hi i have some sort of problem i've had a really weird period it was really short and light, i also feel really sick at odd times of day ?

Any chance of preg.?: 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 having a weird period. An Ob-Gyn doctor can evaluate any persistent or worrisome symptoms.
