Start bd'ing on cd11?

Vanessa🐘 • Mommy of 1 💙🐘 Expecting #2 Nov. ‘22

A friend of mine, who has a 3 month old, told me her doctor told her to bd on cycle days 11, 13, 15, 17 for best chance of a bfp. Not to worry about a positive opk. It worked for her!

Just wondering if anyone else has heard of doing this??
