Glad you've found the thread of use, as have I!
You're early days mate and it's fantastic that all your tests have come through clear. Stress and anxiety will play a massive part in it, and the longer it goes on the more stressful it gets so its a viscious circle. As I've been told many times, just got to try and have fun with it, not over think it. But I do get that that is difficult.
Personally, I've now been tested twice, one post our first fertility appointment and tmit was a bit more conclusive. My guys are an odd shape so looks very likely that we will now be going down the IVF route.
We are waiting for my wife's last tests results to come back before our 2nd appointment at the clinic. That test was one we paid for which isn't on the NHS which depicher how many eggs she has (or something, there was loads of info flying about!)
Its a shitter that it won't happen naturally for us and that the element of surprise is kind of taken away, but i guess that's not important.
The we have started to see it is, we must really want this child to be doing this and hopefully, if we conceive, my son or daughter will know how much they were wanted.
