I temped for 6 months and figured when I Oed, I have very regular cycle which helped.
I would then
DTD 2-3 times over a 5 day period 3-4 days pre O, and 24 hrs post O.
I fluked a
PG first go, but that ended in m/c, it then took me 6 months to conceive DS1. Then when we decided to try again we again fluked it first go, but it also ended in m/c, It then took another 5 months to conceive, I'm currently 12 weeks and all is well.
