Hi Sam and welcome,
The whole IVF thing can be scarey, but when you start to chat and know what goes on it makes it alittle easier. Im currently on metformin at the moment, apparently is lowers the risks of GD in pregnancy. You had any side effects yet?. There is also a thread on here regarding Met in the PCOS and Endo section the ladies in there are also lovely and happy to help out. My husband and I undertook IVF with ICSI and have a beautiful daughter as a result. As far as prices go they do differ depending on whether the IVF is private based or hospital based.
Hope your stay here is enjoyable BUT not too long.lol
