Hi mumalah, I had a look at your chart and I honestly can't tell what's going on, particularly as you've had + opks. Were they definitely +? Or close to? I wonder if for some reason your body has been gearing up to ovulate but the egg isn't being released, therefore no + preg test and no Af.
How frustrating for you.
Have you talked to a doctor about it? Perhaps have your progesterone levels looked at? The temperatures seem to suggest that you have ovulated, but by now you should have a + pregnancy test or AF. Have you ever used the service on Fertility friend where an expert looks at your chart? I can't remember where it is, perhaps in the forums? There are loads of people on Fertility friend with heaps of experience, perhaps they can help.
I am also wondering if you are interested in taking provera to jump start AF, then trying clomid? I think you may have used clomid before?
I feel for you as I know you just want to get on with ttc and getting pregnant. This bloody TTC business is full of frustrations and bumps in the road (instead of bumps on our bodies). 
Mozza, ((hugs)), wow, I am sorry to hear that things are still very difficult for you. I would love to kick your DH up the bum quite frankly! I cannot believe he would consider taking your DD away soon after DD2 is born. WTF is he thinking? I know that you are both faced with an uncertain future, and you don't know how your new baby will be, but isn't that why he should be sticking around to support you?
If I were you I would certainly not allow him to have the passport.(In fact,I would be putting it in a safety deposit box or giving it to a family member for safe keeping) I fear that if you don't he may take DD1 and not return. I know it is important for DD1 to meet his family, but I am sure it can wait a bit longer.
Do you have family support nearby? I hope you do, or friends, as this must be a very difficult time for you. I am so sorry that you have to go through all this.
Jbrd, how are you feeling lovely? I do hope you are having strong symptoms.
AFM, I think I may be about 7 DPO. I have had the usual bag of symptoms, some of them have me a wee bit hopeful, but I keep reminding myself that it is unlikely and I've been through this before to no avail.
Good news is the diet is working, and I am the lowest weight for about ten years. I am pleased with that, but I have a ways to go to be at ideal weight. And if I had to put on weight while gestating...that would be fine!
