I took advice from a post and I have to say, I can’t recommend it. Given this woman got her BFP from this. She recommended that you BD at night and then don’t clean up don’t get up don’t pee. Just go to sleep.

My husband and I BDed last night with pre seed (its my fertile week) and I woke up in the middle of the night and I felt like I had peed the bed. It was so gross. I’m gonna say if that’s what it takes, I’ll have to find another way. Besides I think you can get a UTI that way. I know that ladies get a BFP while still cleaning up and peeing after sex so, just a word of advice from me, stick with your normal post BD routine.
