Pregnant for ten days, took metronidazole and cephalexin for a week. What effect does it have on the fetus?

Patient's question:

No

Doctor's answer:

It does have a certain impact. It is recommended to have a B at around 12 weeks of pregnancy to further understand the development of the fetus. If necessary, an amniocentesis can be performed at 16-20 weeks of pregnancy to further confirm the diagnosis.
