Hi Meh. I feel for you. It must be hard without being able to discuss it with him. My husband is not the most emotional person either but I don't feel as alone as you sound. Do you have any friends that you could talk to? Or perhaps a councillor? My hospital gave us contact details for a councillor right at the beginning, in case we need it.. Have you tried to take your husband to the doctor - so the doctor can explain to him what you are going through, if he cannot understand it when you talk to him??
I'm 39, never been pregnant although we've been trying for years. I've had 2 IUI cycles few years ago but really stressed me out when they didn't proceed due to slightly over reacting to the medication. After years of reluctance, my husband finally got ready for artificial insemination (he didn't really want a baby, as he already have an 18yr old).
Due to low sperm quality they didn't even give us the option of IVF, went for ICSI immediately, which is a bit scary really...
I had 8 (+few small) follicles, had 5 eggs collected, 4 fertilised but only 1 survived till the transfer on day 5 - TODAY! So I'm keeping all my fingers / toes / eyes...

crossed as this may be my only chance. Pregnancy test due on the 11th Oct.
If your doctor recommends you to wait another cycle probably you should. More follicles you have higher the chance of a good result! Look at me.. 1 blasto out of 8 follicles, although as I said the sperm quality is very low here so that may be a reason too. Hopefully you won't have that problem.
Good luck and chin up! Stay strong and look after yourself!
