After BD, when my husband releases inside and then comes out, I am keeping my legs in the air, close to my shoulders (on good days when I'm feeling flexible) or in a 'happy baby' yoga pose for half hour. I've been doing this every time we BD. There is some amount of some white stuff that comes out when I sit up after a half hour. It is the amount and size of the width of my first finger. Is this normal? It could be cervical mucus but I believe some is sperm too. Anyone have this happen to them? Will it be a problem?
