BD'd the night before fertile cm...?

BDing on fertile days give you a 20-30% chance each month as it does every healthy couple hon!!!! Best of luck and lots of sticky baby dust to you!!! Hope you get your BFP soon!!! Don't get discouraged though, it can take a normal, healthy couple up to 12 months to conceive.....just relax and keep trying if you aren't and congrats if you find out you are in two weeks :)
