Swollen Feet At 10 Wks Pregnant Should I Take Maternity Leave Early?

Should I take maternity leave early? - swollen feet at 10 wks pregnant

I am currently 27 weeks, and I started swelling of the hands and feet. I had to wear my rings. My back hurts when I walk. My employer does not seem to make accommodations in the workplace, even though my doctor gave me a note that they do not lift over 10 pounds. I have more work than they had before becoming pregnant and that stresses me. Nobody wants to move boxes, which are more than 10 pounds and I help push with my feet.
I have also asked to work 1 1 / 2 months part time, after her return from maternity leave and is not a definitive answer. I was told that his concern was that my baby is my priority ... Well, of course!
I do not know whether the way back. If I knew that if I work, PT would make things easier. My job is protected by 3 months, but if I did not come back anyway, he can also ask my doc soon move out, because it is too difficult because I'm pregnant. What would you do for me? We have enough $ for 1 years ...
