That's ok, we are here to help! Everyone here is really friendly and helpful so ask away.
We didn't really have a plan for sex days, but we generally both want it a lot and tend not to go more than a couple of days without through my cycle. I try to make sure we are well covered in the fertile window, usually start making sure we aren't going less than every two days the week before and try to go every day when I think ovulation is due (difficult for me as my cycles are an irregular nightmare.).
This cycle I ovulated on CD17, we dtd on CD15 (we did before this too, but although they say sperm can live 5 days I have my doubts as to whether they can in me as I'm quite inhospitable, so I don't think any earlier would have counted towards it!), CD17, CD18, CD19. I was expecting to ov on CD18 so was slightly annoyed about missing day 16 but it obviously didn't matter.
My cm is way out of sync, I tend to get mine a week before ov. I did mention this to my fertility clinic but they didn't seem concerned (and put it down to my pcos and my hormones being a bit out).
