Hopefully my Rainbow Baby!!

So since my first daughter in 2013, I’ve always been high risk, i was put on bed rest at 4 months and then hospitalized till i had her. she was premature weighing only 2 lbs 3 oz. I had a miscarriage a year later at 2 weeks then last year my second daughter was stillborn at 5 months, i worked the whole time and sometimes i feel like it’s my fault cause i knew i should of been on bedrest and doctors never put me on. But We ended up getting her cremated. Now i am pregnant again hoping this is my miracle rainbow baby. I know with this pregnancy i won’t be able to work past maybe 3 months. Has anyone been in similar situations.
