Period is suppose to be the 25th. but i've been tired, sensitive to smells, and constipated. i have clear discharge when i wipe. could i be pregnant?

Hard to tell...: 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). Tests are sold in stores everywhere. An Ob-Gyn doctor can evaluate any persistent or worrisome symptoms.
