Clara - I did read 'it starts with the egg'. I'd been taking folate within another vitamin but took it separately and with a pregnacare tablet (their very expensive one has both).
I'd been tracking ewcm for many months but then really stated to carefully look and record, which I think has helped with timings. I did epo for the first time till ovulation. I also started testing opks 3 times a day near my fertile period which helped catch a positive (my first ever!) I did also notice a tiny bit of streaked ewcm post ovulation which I've seen before.
I used fertility friend and took temps (not always accurate) to try to work out timings.
And I actually dtd every day over 4 days, which ended up being the day before the positive opk, they say of the opk and two following days.
Id previously used conceive plus with my first son but I do think the epo really helped improve my ewcm.
We were considering q10 if this one didn't work. I might if it doesn't stick.
