I've had two rounds of IVF. Appointments will vary depending on your clinic but you will need to attend for scans fairly often before egg collection - I had about three or four in total each time. I sometimes managed to get these done before school though. You'll need time off for egg collection and embryo transfer (and I've always had the time in between off). It's then a case of how long you rest after embryo transfer - it's a two week wait until the pregnancy test. Some people have all that time off, some only a few days. I would echo what Emmsie said about the fertility treatment thread - it's brilliant.
