Anyone wish they could find a BFP right after BD?

It's my fertile week, and right after my husband and I baby danced last night he asked if I'm pregnant now (jokingly of course) and all I could think was I wish they could invent a test to take right after having sex to determine if you're pregnant. It would make life so much easier than having to wait a couple of weeks for AF to show or not show. Who's with me on that invention??
