Thanks Spring, yeah I had a feeling that was the case too... but what is considered too much or too little? I just want to do exactly the right thing. I was wrong by the way I think I am due to O on Sunday. The O calculator tells me we should start DTD on Friday through to mid week the following week but yet I remember when I was at the dr (you know the one who was giving me tips on positions ) he told me we should NOT DTD for a couple of days before my O day for the same reason as you just said. How do we know the right thing to do? Especially when the results show DH has 90% poor quality sperm, how do we get it right? Aaaaargh
