Dh and i are somewhat following shettles method to sway for a girl, so i tracked my last 4-5 cycles so we could time it and according to that i O on CD15. So come actually ttc we dtd CD13 thinking that should be fine but according OPKs i didnt O until CD18 this month. It will be 3.5-4 days after we last dtd. Is there any chance there was still anything there to catch the egg. Weve concieved first month each pregnancy (3) when we just go for it
