IVF timeline

I’m trying to get a better sense of the timeline for IVF. This is my first IVF cycle. I have ultrasound and bloodwork on 3/13 with plans to start my stims on 3/13. I have my next appointment on 3/16 for blood work and ultrasound again. I was told to expect my retrieval sometime between 3/24 and 3/28. The plan is to do a 5 day frozen embryo transfer. We will also have PGS testing performed on our embabies. So should I be expecting my transfer to occur in April or in May? Ladies who have done IVF before what was your timeline like? How much time between stims, retrieval, and transfer?
