Anyone had one while pregnant and did you treat it with over the counter Monistat / Canestan??

I have had intermittent spotting throughout pregnancy and of course 3 weeks no spotting and finally I was able to have sex and we did 2 days ago. Then yesterday I treated self for a yeast infection and now tonight I am spotting a little but no other symptoms.

Sigh so frustrating since I know if I go in to hospital they will tell me the same thing they always do, the baby is fine, cervix is fine, and that it is unexplainable.

Anyway just wanted to vent as I am frustrated!!
