I'm six weeks on Wednesday and after having had a miscarriage last year, I'm totally paranoid that this will go the same way again.

I've done two tests, one 18dpt and another one 24dpt and they were both positive, but I keep expecting to start feeing really sick and 'pregnant'.
I've had cramping, quite bad last week but not too bad now and I feel a bit queasy but not exactly nauseous, mega hungry (that's why I think I'm queasy), loo trips have increased a bit and I have had a lot of heartburn.
My poor complexion is awful too!

But I just expected to feel much worse than this. Has anyone sailed through these first few weeks and gone on to have healthy pregnancies?
Am I worrying too much?
Any advice would be great!
