Pugmum welcome! So IVF is different for different people. I think Pez did a IVF lite cycle, so I think thats light levels of medication.
IVF has 4 main forms. (the below are very high level overviews!)
Long Protocol: 7wks ish start to transfer, lots of meds including down regulation where essentially you are put into menopause, then brought out of it, then stimulated, then egg collection, then embryo transfer. (Ive done this and it was a little hardcore in terms of meds side effects (hot flashes on the down reg! so many eggs I felt like a salmon pre collection...but the results were good LOADs of eggs.)
Short protocol: 2wks ish from start to transfer, lots of meds, no down regulation, but straight to stimulation, then egg collection, then transfer. (Ive done this, and loved it! so easy compared to long protocol)
IVF Lite: Pez can give details, but from my understanding its 2ish weeks - light medical stimulation, then egg collection, then egg transfer
Unofficial hybrid: What Im about to start on: 4wks ish from start of meds to transfer. Loads of meds, steroids for lining growth, basically 'lets throw the kitchen sink at this' kind of thing.
Most clinics seem to use a long protocol as a standard starting point, so find out which one they are considering for you.
I didn't do any IUIs, I went straight to a long protocol.
Ive had the counselling and actually it was helpful, it talks about the terms to use with your child in reference to the donor, and really just allows you to talk about any queries you have about how to normalise this situation to your child and to others. I was very sceptical about it, but actually found it super helpful. In fact it was during the session that I decided to write my child a little bedtime story to read them every night about the choices I made and how they came to be.
Its also useful for how to answer questions from other children.
This sounds odd and honestly I thought that the school yard was more diverse than it is, but still some of my friends children have no idea of a family unit outside of 2.4kids and married mum and dad! (they have so many questions about why Im single its hilarious!) So I feel a responsibility to educate children outside of the family within my friend zone that there is no normal in order to make things easier for my (hopefully soon to be) child.
Its also handy to get ideas on how to arm your child to deal with other kids questions about parentage which crops up from a very early age.
I say go with an open mind.
So any other questions re ivf let us know! As Im about to start my third round so Im feeling like a pro now! but others have done it too.
