I realised I'd misread the question.
So on the 8th cycle, both times, I thought it just wasn't going to happen and had given up.
During my time ttc I did the following: Brazil nuts, pineapple core, ovulation tests, temping, acupuncture, fertility lubricant, legs in the air, moon cup after dtd, all different positions, coq10 tablets, evening primrose oil tablets, some vile tasting fruit juice in the first half of my cycle that I can't remember the name of, SMEP. I'm sure there were more things. Truly, none of it really works, it's just when the right time is for you.
I asked this same question the other day as I'm ttc #2 but in my experience there's no one set thing.
