Question on protocol....

I’ve had my consultation 1/29, the day of consultation my doctor took a blood test (FSH) - which is 3.2 , doctor made up or plan a couple days later (which I don’t have in writing and they don’t give it yet)

I’ve got the BC on the counter to start 2 days into my period, then we will do a trial transfer/saline sonogram. They say I will still on the birth control up to 3-4 weeks (4 at most)

Can anyone tell me the next step after the saline sonogram/mock transfer ?

Curious to when we actually can start- we are going as quick as they let us
