Not allowed to drive?

I got 4 weeks to go and am diagnosed with mild preeclampsia, so I got to monitor my blood pressure and have water retention especially legs/feet and barely can walk- I eventually feels more pressure, numbness and burning sensation. My check up is tomorrow and some family members offer to drive because I shouldn’t be driving on my own anymore, they say it’s dangerous. I have an issue with asking and accepting offers. I am not completely bed ridden so I don’t see this as much of a big deal
