Pregnancy Info HOME

So I receive a call from my local health department last tuesday. the man on the other side of the line says that one of the tests that i received on my two week check-up came back positive for chlamydia. note, i havent had s_x for about 3 months, i am married and have received prenatal care, and numerous tests and none of them came back with that diagnose. i went to receive care the next day, and the nurse there told me since i had just given birth a month ago, that our bodies go through all sorts of things and hormonal changes, and that that is why my body could have guiven that signal. i got medication anyways. is this even possible? should i gind another doctor? please help, i need some input.
