I don't think I did the pillow thing either.
You have to remember that sperm can't "fall out" of you - even if you get the drips right after sex!!!!!!! Even if you pee the moment after sex!
There are way too many "wives tales" out there I think, that confuse us as to what we should do in order to increase our chances of getting pregnant!!!!!
As long as you and partner are healthy and actively trying on your fertile days, it will happen to everyone eventually!!!!!!!!!! That poor little sperm has to make it with perfect timing and it doesn't always happen - but remember that it only takes one sperm!!!!!!!!!!!!!!!
Keep that chin up girl - I wish you tons and tons of baby dust!!!!
Keep us posted!
