I'd be really grateful if someone could offer a little advice.. I had unprotected sex on Saturday and think I ovulated today. What do you think is the likelihood of my conceiving? At the back of my mind I knew on Saturday I was taking a risk as I was mid-cycle, although I didn't feel I'd ovulated. The relationship is on shaky ground, but in a way I'd really love another child as I'm 36 and DD is nearly 3... Thanks.
