I'm still waiting and hoping !!! Having IUI in a few days hopefully!!
It all depends I took femara one cycle with injectable (ovidrel) & an iui & worked on the first try. I'm 5 weeks & 3 days today. Clomid works but not for everyone clomid often thickens the cervical mucus which makes it hard for the sperm to swim to contect to the egg. I was taking tussin as well my last cycle of clomid but it didn't work. I had 6 cycles of clomid three solo & three with iui's. I wish you the best of luck.
I just got pregnant on Femara - it wasn't my first time though. I also had IUI.
Good luck! I recommend it much more than clomid - clomid is the devil!
