Is monistat 7 safe????

5 weeks pregnant, yeast infection. 😭😭 The nurse said to get monistat 7 and use the internal cream but not to stick applicator in too far. Is this safe?! I’ve read things like “no it’s not safe!!!!” And I’ve read things that say it’s perfectly fine. I’m confused on what to do. I’ve had a miscarriage in the past and don’t want to risk having another one. PLEASE COMMENT.
