Terconazole
"I was told it was safe by my OBGYN even though I was only 7 wks pregnant. Went against my gut instinct, trusted them resulting in my miscarriage during the 3 day treatment. First treatment I administered was right before bed, and I started mild bleeding by the next morning (mind you I had no bleeding or complications before this). Didn't even have symptoms of a yeast infection so it was mild at best. Wish I never used it."
