Church Conundrum

So my husband is a preacher. I've had a hard time attending services. I've seriously puked my entire pregnancy. I'm due first week of May so I have about 3 weeks left. 
Now, this would all be fine. After all, pregnancy is temporary. But our church parishioners have been kinda ugly about my lack of attendance. Prompting my husband to even ask if they wanted me sit in the front pew with a puke bucket. 
I went to my OB and he said if I was working full time, he'd put me on bedrest. But since I'm at home, I'm supposed to take it easy. Keep off my feet, lay on my side, and rest. 
The church suddenly decided to throw me a Baby Shower. Nobody asked me. They just informed me they were doing it, when it would be, and I was to be there.  They were extremely generous despite people even being rude and ugly to me and my mom at the shower. She has come up to help with my kids since I'm supposed to be on such light duty. I'm extremely thankful for her help. I didn't come to the two hours worth of services before the shower because I can barely stand. By the time the shower was over, I was in so much pain I could barely walk to the car. It's embarrassing, but they don't have any understanding. 
All I did was sit at the shower, and by the time I got home, my husband had to help me stand. I was in tears. 
Fast forward and we are entering the Easter Season. This Sunday is Palm Sunday and Holy Week. My husband will be serving all week and into next weekend. It isn't that I don't wanna go. As a woman of faith, I want to be there. But I'm supposed to be resting. My church is 226 years old with the original pews. Rock hard. It hurts every inch of me to sit there. Sets off the pressure of how low the baby is. Even with a pillow to sit on. 
But I feel like they've thrown this shower and me not coming to worship for the next three weeks especially after the comments like "it's about time you showed up to see what we've planned for you." And it being a huge weekend where my husband needs my support, I don't know. Our people have been so unkind my whole pregnancy...even telling my husband they didn't ask us to get pregnant so don't expect any extra money to help. (We never asked for anything extra. Nor for a Baby Shower.) 
My mom seems to think I need to be there. Push through. Make appearances. And if I have to, leave early. I feel like the Almighty is understanding, and has given us this blessing. But the idea of setting off the pain when I probably should be on bedrest and being unable to stand or even move around the house is upsetting. 
Am I selfish? Should I suck it up and push through? Or is it 3 weeks until I'm due and follow the bedrest?
UPDATE: Just for the record, my husband is my strongest defender. He has been infuriated with their comments and treatments of
Our littles life and me. But I don't always share with him comments until after we get home. No man could stand strong in the pulpit if he'd known what was said to me right before. I've had to talk him down from calling them out from the pulpit over stupid things said. I don't want World war 3 because of my family. And it is heartbreaking. What hurts is a lot of things have even need said in meetings and someone even sent an anonymous letter complaining I'm a bad pastor's wife because I'm not faithful to attend and serve through a difficult pregnancyHe wouldn't even let me see it. Not every body of believers is healthy. Some are very hurtful to their leadership. As has been the case here.
