Bled for 3 weeks (may). no period (june). 3 day period (july). on bc pills. starting period 3 days early this month (august). normal or pregnant?

Maybe not preg., but: 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 a few days after she misses her expected withdrawal period if on birth control pills.
