Good evening, i missed my period for 2days after having unprotected sex, but my period came after taking augmentin for uti. could i be pregnant?

Pregnancy unlikely: 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. If a woman has her normal regular period, then she is not pregnant.
