I agree that you should phone your FS and find out what's going on. If you have an AF for that long it must mean that your hormones are out of balance for whatever reason. You may need some other medication to get things back on track. If you did O while you had AF I imagine it would be difficult to have a successful pg as the lining is being shed.

My FS did things quite differently when we were TTC #1. I was monitored closely with BTs and if the BT came back that my hormones weren't responding then I had more Clomid. The first cycle I started on 25mg it then got upped to 50mg and then I had a 2nd lot of 50mg. I ended up Oing on CD29 (a record for me ) after taking 5x25mg and 6x50mg tabs. The 2nd cycle was a lot better - I started on 50mg and took the initial 5 tabs and then had a further 3. Once again I was monitored with BTs and this time also an U/S. I also had a trigger shot. That was the cycle we conceived DS. As far as AF went I only had the one AF on Clomid. It was short (3.5 days), painless and arrived on 15DPO.

The stats for conception on Clomid probably aren't that great as a lot of women needing Clomid to O in fact probably have other issues inhibiting conception too. Clomid makes you O and that's about it - can help lengthen your luteal phase though.
