IVF process ?? Confused!!

Danielle

So I went for my Cycle day 3 testing and I go on the 5th to have an SHG done. I have 19 follicles on my right and 15 on my left. And blood work came back normal. Can someone please explain to me the process of IVF. I've been told that my CD 3 testing starts the "cycle" of ivf because that's my baseline tests. Is this accurate and if so, what comes next??
