Quick update. After having got our results the other week DH finaly decided it was time he told his parents. I was very anxious about this, but hi Mum was aparantly very supportive. She told him that they tried 4 years before he was conceived, and that he was a clomid baby! My dh is the oldest of 3, so I don't think they had too much trouble after him. I was worried she'd suggest we hold off IVF until I've finished uni, but alas, they didn't mention it, but rather said that they would always be there if every we needed help - emotionally or financially. Pheew. D/H is also very relieved and seems a little more relaxed now.
Feeling blessed to have two families that care about us so much, and can't wait till the day we can bless them with a grandchild, niece/nephew, cousin, etc.
