I am feeling pregancy symptoms but both of my pregnancy tests are negative. is there a determining symptom of pregnancy that isnt related to pms?

Not early on: 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 home 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. These tests are very accurate.
