Hot fed up and uncomfortable

I am nearly 19 weeks and I am just so fed up My stomach hurts feels so stretched out, constantly hot and bothered and seriously fed up I’m not sleeping pee 100 times a day there is nothing to do I am supposed to be taking it really easy as I had 3 previous pre term babies I have another 18 weeks until section date and I’m so bored 😩 I started knitting and I’m fed up with that as I was put on bed rest at 12 weeks now I can move around but have a wheel chair for going which I don’t do

Much off as my husband works 6 days a week and I can’t take myself and 3 kids out like this I’m just so stressed out
