Definitely get a second opinion. I can’t push blind hope at you – because something is obviously wrong here. Do you use BBTs and ovulation tests? What are your results like with this? Do you see a thermal shift? Do you get positive OPKs (or are they persistently positive – suggesting PCOS)?
I would see a reproductive endocrinologist at this stage. I am assuming you’ve had all of your basic bloodwork, and your opening post suggests you’ve had an SA for him. What about an HSG (to check for blocked tubes)? Have they done a post-coital cervical mucus test on you (i.e., you go in after having sex. Sometimes, a woman’s CM isn’t receptive to his sperm, which would mean IUI might be a necessity for you to get pregnant)?
Have you ever had a round of IUI? It’s totally covered on my insurance, but out of pocket, I think it would be $700 – $1k. That’s not counting an HSG, though, which you’ll need first to even get to IUI.
How old are you? Do you know about the condition of your eggs? If you haven’t already had it, talk to an RE about getting an Antral Follicle Count and having your FSH/E2 levels checked. I don’t know your age, and it’s unlikely anyway, but there’s a possibility that you may not have as many eggs as you think.
I really wish I could give you well-wishes. I only know of one couple who tried longer. One of my husband’s co-workers was trying for 10 years, and though I know it’s trite, she actually WAS beginning the adoption process when she found out she was pregnant. But I also don’t want to push false hope at you – the odds of conceiving are drastically lower in your position.
If you haven’t seen an RE yet, please get in to see one. My SIL was stalled by her OBGYN for *years* doing blood tests and he would just shrug and say, “I THINK you might not be ovulating…” or “I THINK there might be a cyst on one of your ovaries…”
Never suggested BBTs or taking ovulation tests to actually rule that out to her. Or even getting advanced treatment. When I mentioned an “RE” to her, she asked, “What’s that?”
Some OBGYNs will never refer you – because some of them want to keep the business.
