BD Day After Ovulation?

Anna

I know I should BD the day after ovulation to maximum my chances... But I'm sore! I got 3 days in this fertile window, which is less than I intended (my +OPK came sooner than expected), so that's why I feel like I should get another BD in before my window is over. But I know I shouldn't force it if I'm in pain. Ugh. But I know I'm gonna be mad at myself if I get another BFN.

How important is the day after ovulation to you guys?
