I've dealt w/ the same issue I try natural stuff after that. I don't have this anymore.
HI, I cant be sure why you got the yeast infection the first time but the second time you got it was probably from the antibiotic as this can cause yeast infections. Whenever I have to take an antibiotic I always make sure to take diflucan after the last antibiotic.
You said you did not have sex for about 2 months before these symptoms started but are you having sex now? If you are you may have passed the yeast infection over and there is no point in you treating yourself unless your partner also is treated, otherwise it will just keep getting passed back and forth.
There are other things that cause yeast infections that you may not be aware of such as using contraceptive pill, using perfumed body wash in that area, wearing pants of jeans too tight. Also too much sugar in your diet.
If it continues you should talk to your GP about it. I hope this helps. Good luck
