Thanx Jo, i am hoping you will have some good fortune soon. Either with another doctor for DH or a BFP.
I was curious because my hubby has two kids from a previous relationship and we have pretty much assumed he is all good because of them. It goes to show that stuff can happen in between thou.
Our problems come after we concieve thou, so i take most of the blame for that on my shoulders.

Keep positive and i am sure it will happen again for you ! Like you said, it's happened twice before!!
