Terconazole Vaginal cream 0.8%

I have an upcoming Cerclage surgery appt and noticed that I have developed a yeast infection. I Have the Terconazole vaginal cream that I picked up a week prior but didn’t use bc my symptoms went away. It didn’t dawn on me to look up any side effects until I already used the 1st tube. I am at the end of my first trimester but still currently in my 1st trimester and upon looking up the information it states not to use in first trimester and that it overall is not safe during pregnancy! I am now extremely nervous!!! Has anyone else been prescribed this medication while pregnant?
