amummyinwaiting you are very welcome on this thread. I find it does have its quiet times when nothing happens, but then it picks up again. For me it is very difficult to get online to do any proper posting, as I am either at work or have no access to a computer and have to rely on my phone, which is ok for reading posts but not terribly good for replying - particularly one of those spectacular replies where you list everyone's name and address them personally!
You are so not alone in feeling the way you do, it is not that long since I had a similar crisis of confidence and blubbed my heart out on the thread about not being sure what I wanted. It doesn't mean we are not going to be mums, or that we don't really want to be - I think it's just natural to feel overwhelmed occasionally when contemplating ttc 24-7. Once you've made up your mind to do a bungee jump you don't want to be hanging around at the top looking down for months, you just want to grit your teeth and get on with it, whatever horror might await you!
My DH has just got a new job too and is also on a 3 month trial as of Monday. I would also like to start ttc in January. DH has not agreed to this yet. I have always been the one driving this.
We don't own our own house, and we're a long way off doing so, so it seems rash to start ttc. But leaving it any longer when I possibly want to have 2 children is really becoming out of the question, if only because I don't want to have to wait indefinitely. Also, if you read enough posts on MN it becomes obvious that no matter how much planning you do, you can't control what will happen tomorrow.
Like your DH I have quite a lot of debts - much more than your DH actually. They are manageable, but only while I have a wage coming in every month. I couldn't afford to pay them out of statutory maternity pay, which means that unless I save up a lump sum, DH would have to take over my repayments for a while - and I don't want that.
I wouldn't worry too much about your weight. If you are fit and healthy that's the important thing. Take on board reasonable health advice up to a point but tell midwife/HV off if he/she gets too judgy.
If you have read my posts you will know that I am also having horrible problems at work with my boss. I don't want to change career but I would like to go elsewhere - and the timing is terrible.
But at the end of the day, like you, I want to have a child. I agree with what you say about your DH - and that is what we are here for, for you to spill all your fears and worries, so that you can present a positive, if not bordering on obstinate front to DH.
