29 weeks and one baby girl

I am 29 weeks due with one baby girl. I'm measuring 4 weeks ahead with alot of amniotic fluid. also baby girl has a heart defect that they cannot figure out which surgery needs performed after birth because it is something rare and unheard of. this is Riley Hospital that is saying this. I am in so much pain and so uncomfortable... this is baby number four. The whole top of my uterus is numb. My first two babies I worked all the way until my due date. My third baby I worked until he was born premature at 35 weeks gestation. I am to the point I just feel so uncomfortable and miserable at work plus come home and take care of three children... my husband makes plenty of money so I could take an early leave and we will be more than financially stable, but for some reason I'm just feeling so guilty every time I think about making this decision. after working for 1 hour I feel completely pooped and in pain and sometimes start having contractions that are unbearable because they are painful. I start getting light-headed and dizzy, lifting becomes very difficult. someone please help me get over feeling guilty for wanting to take an early maternity leave. Due April 29th 😢👣🤰🏽
