Poor you :( both of you, it must be a really hard situation.
Personally I think advising you to have sex every other day and doing 3opks a day is far too much. Could you just try to take the pressure off you both and aim to have sex twice midcycle?
Do you ever ovulate on your own? Did you need Clomid for dc1 and the baby you miscarried?
I know how infertility feels, both me and dp have fertility issues and it took years to conceive ds, I hope you are not offended by me suggesting that you relax.
We were told that I wouldn't ovulate the cycle before we were due to start ivf ( internal ultrasound, the Dr saw no eggs maturing) we went on a skiing trip, drank lots and didn't have planned sex ( just spontaneous sex) and I got pregnant.
We had spent years having dull baby making midcycle sex, it just didn't work for us.
Can you take a break for a couple of cycles? My Dr said they would prescribe Clomid for a maximum of 6 cycles, it seems a waste to be using up you cycles if there is no hope for sperm.
You could possibly start taking the Clomid again and not tell your dp? Fertility treatment really isn't sexy unfortunately.
Best of luck, I am sorry for your loss :(
