Discrimination at work

I work at a McDonald s in my town and they keep on treating me different since I've been pregnant. Im at a high risk to miscarry. So my doctor doesn't want me doing any physical activity until my second trimester. And my job tells me that I'm milking it basically. They want me to carry the three gallon tea container s full and I refuse and then the mangers son told me today that I should be burned at a stake today because pregnant woman can chop trees and I won't carry a three gallon tea container while its full. I've already turned in my notice because this place is so toxic. My last day is the 20th but I don't even wanna finish it through. I really hate this place. Advice on tolerance for my last 14 days.
