This is the first month that we have been TTC seriously and DH we have decided that we should do it as much as possible to have the best shot. He seems to be under the misapprehension that the more we do it, the more pregnant I'll get 
But I'm knackered! Admittedly we did get a bit over enthusiastic a little bit early because DH can't count but even so. And I read some threads where there are people that do it every day all the time 
Where on earth do they find the energy?!
