Okay.. question..

I've been trying to conceive for about 1 year now. I track my ovulation with a kit and everything. For some reason me and my hunny never seem to BD the day OF ovulation. This month we BD the day before ovulation and I elevated my pelvis and everything. When i tell yall i try all the tips and tricks, I do. Between OPK, taking mucinex the week of O, pills to thin out mucus.. everything. Okay, so my question is.. has anyone only BD the night before O and been successful?
