Question

Britt TTC#1 🌈

A girl at work has been trying to give my tips on how to conceive. She said it’s best to try not to have sex until your 14th day. (Making sure your partner doesn’t “go” until then) she’s telling me it’s best for him to wait that way there’s more sperm built up. ( last time I was in my fertile window and TTC on just about every day with no luck, so now I’m wondering if this has some truth?)Has anyone heard of this, or have any input ?
