persistant thrush in breasts and vaginal

Hi, I am looking for help with some persistant thrush.

I have an 18month old who is not presenting any symptoms. My symptoms fluctuate with the month.
After my period I start to get increasing pain in my breasts. Nipples and ductal shooting pains towards my back. But worst in my nipples. It is worst when breastfeeding and for a few minutes after. Worse for being touched. Worse in the evening and especially at night.
It peaks about 2 weeks after my period and then goes away within a week.
Then, about a week before my period I get vaginal symptoms, not too severe. Mostly itching and a mild discharge. Also a heaviness in my lower tummy/uterus.
This lasts till about a day after my period starts.

I have been having these cycles for 6 months. I am taking pro-biotics and GSE as a wash and internally. I have been taking Nystatin tablets since December.
I have been eliminating sugar from my diet.
I have just started treating my toddler with Nystatin liquid.

Please help.
