My doctor gave me Norfloxacin 400mg dose twice a day for a yeast infection during my first week of pregnancy wthoutout knowing I was pregnant now that i missed my period and took the pregnancy test which came positive I know that i must have conceived a week before I actually got the thrush and went to the doctor saying I probably had the yeast infection and had passed on to my partner when he gave me Norfloxacin without checking if i was pregnant. Now taht i have read about the effects on the fetus and I am already in my third - fouth week of pregnancy I am worried if I should keep this pregnancy or is it going to be damaging to my baby. Please let me know i am very worried. i am 28 perfectly healthy and this is my first time conceiving.
