Okay my May mommas


I need help I’ve been non stop throwing up since like Friday nothing is staying down no water nothing at all I’m just in the bathroom drinking sips and puking 15mins later. I’m miserable. Should I call the oB I’m not seeing them for another 3 weeks but I don’t think I’ll make it that far. What steps should I take? Is there anything they can give me? I’ve never had this every day non stop morning sickness. It’s stopping me from being a mom and giving me migraines.
