bacterial vaginitis
"I was given clindamycin for bacterial vaginosis while pregnant.  I had been on it once years before for something else and it made me vomit once and mildly uncomfortable the rest of the time.  This time it has caused throat and chest pain and tightening, rash, horrible heartburn, and more.  Doctor won't give me anything else, but I am beginning to think the BV is of less risk to baby than this is.  Never again"
