February 4th stopped pill & got period. sexually active between feb 13th-17th. bleeding between 19th-21st. nausea, dizzy, tired, could i be pregnant?

Maybe, maybe not...: 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.
