Hi there - I would think all FS's work out of specific clinics, but remember, they want to get you pregnant, it's in their interests to do that as their success rates bring in 'new' business. Personally, I think having the same GYN and FS would be a bonus (assuming you feel comfortable with this person). I went straight to an FS (referral from GP) after trying for a year. Straight onto clomid for upteen cycles, then onto IUI and then onto IVF. Being conservative with your approach is dependant on your medical problems, but in hindsight a lot of people (including me) wish they had gone straight to IVF, but this is an entirely personal choice. Clomid and IUI works for lots of people, just not me. The needles weren't that bad at all, but am over blood tests! I don't have PCOS or endo, so for me being conservative initially made sense, however it took me years (over three) to get pregnant and I started at 30. My desire was always for more than one child, so the earlier I got onto the issue, the more likely I was to be able to have #2. Goodluck with your decision, and if you have any more Q's we are here to help you
