Hi there. Depending on what testing you and your partner need done it can take about 2 months to be ready to go. For me I had all my testing done and then when my specialist got the results back he got us to fill in the forms for WFC then you are sent away with 2 things to do. First you and partner get blood test screening for HIV then partner has a semen analysis done at the hospital. You ring up to book that in. Then a week later the results will be back and you go back to your FS and sign all paperwork and ring the clinic for a nurses interview. I rang up for my interview and 4 days later had the interview and had AF on that day and got started that day. That's because I was doing an antagonist cycle where you start injections day 2. So all together it shouldn't take more than 2 months to get started possibly less depending on your situation.
I am currently in the 2WW with a double embryo transfer yesterday. Everyone is so lovely there I am very impressed so far and this is my first ivf cycle. Good luck hopingforbub2
