Hi OP, I just wanted to come and offer you some support.
My friend didn’t have the vaccine when she was pregnant as she’d gone through IVF for almost three years and in her eyes she wasn’t going to do anything that may potentially cause a risk to the baby.
The price she paid was that she effectively isolated herself for 8 months, she didn’t leave her bedroom unless she was going to the bathroom. Her husband slept in another room and they would only see each other briefly when he bought her meals up for her. He was still going out to work so she didn’t want to risk being near him.
It was a rough 8 months but she preferred to do that than get the vaccine.
She had the baby at term, all was well and she got vaccinated very soon afterwards.
I work in a hospital and as others have said, there are a number of pregnant women quite unwell with Covid (including them having a CS to get the baby out) in the most extreme of cases.
However, you can’t change your choice.
Just get yourself and your children away from your husband.
Don’t feel guilty though OP, you made the right decision for yourself at that time and hindsight doesn’t do anyone any good.
