Pregnancy is like that. You'll be scared then happy then bored (it's endless) pissed off (it can be uncomfortable) then happy and so on.
9 months is a long long time. But it passes.
Just daunder along take it as it comes and keep reminding yourself people have babies literally every day.
Your first job is to look after yourself and just focus on the now.
If it helps, I had 2, at 35, my partner lived in one house, I lived in another. I had endless antenatal appointments, knitted lots of blankets. Gave birth. Went ok. Just coped for the first 12 weeks. Got into my stride after about 3 months. He varied between helpful and being an active hindrance.
Nothing was quite as I'd imagined but I just got on with it.
I went back to work when they were 6 months. They went to nursery. Tax credits were a godsend as I will still living as a lone parent with him dropping by every now and again. He'd said he would look after them one day a week but didn't.
I moved house on my own when they were 18months.
We split up finally when they were 4.
Me and the kids are still managing to bumble along.
It is far from perfect but everyone is fed and no one is dead.
Occasionally they stop arguing long enough to draw breath
We get through each day as it comes along and so far I have a 100% record for getting to the end of the day
We are all clothed and have a home and the odd holiday. It doesn't take a fortune just a bit of a can do attitude. Which comes free with the stretch marks because there is no other option.
Wouldn't change them for the world even though I'd change myself into.a better parent about 10 times a day if I had the choice
