I've read of a few people doing this, and I guess it can't hurt. Some get pregnant this way, some don't. From everything I've read, 20 minutes of lying down is about as good as 8 hours lying down. What hasn't made it up there in 20 minutes probably wouldn't get there anyway. I know the sperm doesn't reach the egg in 20 minutes, but I think they swim past some point where they can't readily fall out. Plus, if you're just getting up for a quick trip to the potty, not ALL of it will fall out.
I hope you don't mind me answering even though I did not use either of the products, but I think your odds are just as good without it. Have you tried using the restroom before bed, seducing your hubby
, and then just going to sleep? That way you could sleep the whole night like that.
