Hi
I'm new here but was wondering this exact topic. I've just started TTC and i get ovulation cramps each month and spot on 14 days later AF visits. This month I DTD (And i hope i get my acronym's right here) and noticed afterwards what i can only assume was CM. 1.5 days later i got cramps so i'm assuming that was OV but i'm not sure if i could have caught that the 1.5 days beforehand. I also DTD the day after OV cramps (wasn't possible on the actual day) so not even sure if that is a chance of catching it.
All so technical really and sorry if my acronym's make absolutely no sense.
