Yeast infection

I got my first used infection approximately a month ago used Monistat one and it went away then I got my period about a week and a half to two weeks later.

A few days ago approximately three I noticed I had another yeast infection so I grabbed the Monistat one again… But instead of it healing like it did last time it seems to be the same except for this time when I apply the topical cream… It starts to itch and burn compared to relieving… The weird thing about this yeast infection though… Is there is no soreness open wounds or itching until I apply the Monistat.

I’m a little worried and I feel bad for my boyfriend… please give advice.

I live on my own at 18 and I’m about to ship off to the Navy in approximately three weeks… Unfortunately I cannot afford to go to a doctor at the moment and so I can’t get it checked out.

Does this sound OK?

Should I not be worried considering it’s only the third day
