My period came on for about a hour and went off could i be pregnant?

Do UPT: You may need to take a home urine pregnancy test. If it is negative, the irregular bleeding may be from some recent stress. Also check your diet for gluten, dairy and processed sugar as this can also stress your body.

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), or 1 week after missing a period. An Ob-Gyn doctor can evaluate any recurring or worrisome symptoms.
