Had one time brown with a bit of pink discharge around 9 days before next period. cycle around 29-31 days. had protected sex 1 week before that (condom, didn't break or slip, ejaculated outside ). pregnant? something else?

Pregnancy worries?: 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 (when conception might have occurred), or 1 week after missing a period. An Ob-Gyn doctor can evaluate any persistent or worrisome symptoms.
