Help please?

Ive been suffering with thrush the past few days so didn't 'start' my period. I had been feeling weird all last week but thought it was due to my period coming soon, this morning I took a test to be sure and it was positive (huge shock to be honest, although I already have a 2 year old) because I've just found out about being pregnant I'm unsure how to treat my thrush! I rang the doctors but they can't get me in anytime soon and we go away on holiday next week for a week. Bit unsure what to do to get relief and treat it!
