I called my doctor but had to leave a message for call back.

I’m 36weeks and 3 days. I have GD that has been managed with meds. So Tuesday I was having pretty bad contractions for like 2 hours and decided to come home and drink water and lay down and they slowed down. Well 5 am the next day I passed my whole mucus plug not bloody show tho and no contractions so I just went about my day. Later last night my feet and hands swelled up bad and haven’t gotten better and I’m having bad headaches. My question is should I go into ER to be checked or just wait for my doctors appointment tomorrow? Also is anyone else having or had this happen to them? I’m not having contractions and baby is still moving a lil. I’ve never had any of this with my last two pregnancy’s. My 3rd C-section is set for September 5th. Sorry so long. I really don’t want to rush to the hospital if this is all normal because I live and hour and a half away from the hospital.
