I had a MMC and tried for 5m before we struck lucky on month 6. I feel for you, trying 2 years. I was much older than you though, so I was demented about the loss, the time it was taking, and my ticking biological clock.
The month we struck lucky, I had given up. I had the worst cold/flu thing. I was talking hot Epsom salt baths to draw the germs out of me. I filled up on co-codamol and decongestants (previously avoided due to the effects on cervical mucus). I drank a lot of cider and wine to kill the germs. I didn't want to have sex at all, but we were on a weekend away in a guest house so after too much cider, and lot's of painkillers etc, we felt obliged to have holiday sex. Nothing fancy, no lying about, pillows under the bum, just drunken coma style.
We were using the conceive+ gel, or pre-seed stuff because we had some, when I'd been religious about it and ovulation tests etc. No ovulation test. No saving up sperm for ovulation day.
I tried to control everything, to maximize our chances every month, then blamed myself for my failure and spent more money on something different. I would have bought magic beans if Amazon gave them 5*.
Please be kind to yourself. Consider a month off. Eat what you like, drink what you like, pee straight into the toilet without catching a sample. Recharge and snuggle your DH, get into a box set, stay up late, be naughty. It's hard work TTC, I will never do it again, I'm still scarred for life.
Good luck, it's a lottery, every one is a miracle xx
