Thrush 😩

Sorry if TMI but I’m losing my mind with this! Has anyone else experienced severe thrush that you just can’t seem to get rid of? I’ve already had one lot of pessaries for 7 days, now on my second prescription as it didn’t work! Doctor said it’s hard to shift in pregnancy…but I’m 40 weeks today, and the thought of giving birth with this is just awful! I’m already uncomfortable enough as it is, but with on top it’s just horrific!! Any tips, advice please?
