Killer yeast infection

Ok, so I have a bad yeast infection. I am 6 weeks pregnant and doctor prescribed me any 7 days cream over the counter so far I had purchased two Monistat and clotrimazole creams but OmG I think I am allergic to all over the counter creams they burn like crazy and make my itch worse. I read a lot that coconut out helps which I bought one and feel the difference. I really hope it helps because I am now getting concerned with the baby and want nothing to happen to my 🌈 baby. Any suggestions?
