Grizzer, hang in there. I know it is hard ttc month after month, but you just have to keep going. Even when you are doing everything right (which must help your chances) I think it is a matter of waiting for the right egg and sperm combo.
I've done another first response test this morning, which is positive, but no darker than yesterday and still lighter than the first test I did at 12 DPO. This doesn't bode well for me. At 14 DPO I usually have very clear positives. However, it is possible that this box of tests (which are different from the first test I did)have less dye,I suppose. I realise I'm grasping at straws, hoping there's an explanation, but the truth is, I don't feel all that positive about it. Although I have the metallic taste in my mouth, I don't have many other symptoms that I usually have in early pregnancy, like tender breasts, nausea, extreme tiredness. I guess there's also the possibility that it's a late implanter. I did have some brownish discharge at 11 dpo, so maybe...
Deige I haven't been temping, though I have taken my temperature once I got up, on the day of the + test and it was very high. This morning (again, after getting up, I didn't have the thermometer by the bed) It was over 37 again.
I've only told my Dr in RL. I cannot see the point in upsetting the balance at home by telling DH at this stage. It will happen when I can no longer keep it to myself, when it becomes obvious to him, or at about 10 weeks when I feel surer
I just don't know how I will start that conversation. I nearly let it slip yesterday. I wasn't going to tell him I'd been to the doctor, but he asked how much DD's visit to the Dr cost, and I told him, "It was $70 for both of us". He asked, "Why did you see the Dr?", and I made up a story of how I'd been feeling tired too, and wanted my iron tested, like DD. I guess I'll use the blood test as the conversation starter (if the pregnancy progresses).
If the HCG isn't increasing (which is what seems to be happening, as the tests aren't getting darker - the internet cheapies aren't even giving me a faint line
) how long do you think it will be before AF comes?
As much as I don't want to think about it, I couldn't help but think about how if all goes well, I'd have a month old baby at Christmas! How wonderful that would be 
I'm sorry I keep banging on about my plight, especially when I know so many of you are ttc, I will go mad if I can't talk to someone about this.
