I have ben havin unprotected sex.. i wiped & saw pinkish/brown blood.. then 2day i have bowel movement and saw pink blood when i wiped.. am i pregnant?

Get pregnancy test: Home pregnancy tests are inexpensive & readily available at most grocery & drug stores. Use one as directed to address your main concern. Then stop having unprotected sex. Notice i didn't say to stop having sex but rather see your family doc about some form of birth control (unless you want to get pregnant) & make him wear a condom each & every time to minimize risk of sexually transmitted disease.

Possibly: If you haven't been using birth control it's possible you are pregnant. But there are a number of other reasons you might have some spotting or blood on wiping. Some of these include infection, hormonal problems, or even hemorrhoids. Check a pregnancy test if your period is late, or if you're worried. And see a gynecologist if you are pregnant, or irregular bleeding continues.
