Dear Doctor, My Wife Is 7 Week Pregnant Now. She

Dear Doctor,
My wife is 7 week pregnant now. She had some bleeding during last week . Suspecting a miscarriage one of the doctor prescribed her Ofloxacin + Ornidazole. She took it for three day. Today we had another test(ultra sound) and it should that the fetus was in good condition. We are happy to know the results.But as she took the medication for 3 days we are little bit concerned about its side effect on the health and development of the baby.
we would be grateful if you could provide some insight on this.
Thank you.
