Did the gynae say why your eggs are not growing? Is your menses regular?
If your eggs are really not growing, you could be having PCOS.
I was on chlomid when I was trying to concieve my baby. I was on it for 3 mths then switched to another drug (I can't remember the name) for another 3 mths at the end of which I got pregnant.
I was also using Clearblue ovulation kit (non-digital) as well as bought some kits from my gynae.
Did you discuss options with your gynae? What did he advise you? Are you also taking BBT?
