Does acne get worse before it gets better?

I have acne all over and under my breast, im larger breasted and its due to sweat, my doctor referred me to a dermatologist but they cant get me in until december, i have been using tea tree antibacterial soap and it hasnt made it go away so i just ordered hiblicans and everyone says its amazing for acne, the first day i used it i noticed two more red spots appeared, if you ever had acne problems, when switching to a new product did it get worse before better? Thanks
