30 weeks preg. terminated from my health insurance!! HELP!!?

i can't believe this. i went in yesterday for a l scan (my cervix is too short and i go in for weekly monitering) and the lady said that i as terminated from my insurance. My father offered to pay f my insurance up until after i gave birth so i am on his Kaiser family plan. as far as i know we have a really good plan i rarely even pay copayments except for labs and even then its only $10. (we got good nsurance after a few family health scares over the years) anyhoo, im 19 and ve been on complete bedrest since 21 weeks preg, i was ordered to 23 hours of bedrest a day. well because of this i couldnt enroll in any cles for fall and the insurance is claiming that if you are over 18 then you have to be going school full time. this is really hard to deal with right now and i need to get it fixed proptly since i need my weekly screenings. ive been told repeatedly that they dont even think my cervix will hold until 35 weeks. what should i do? does anybody know anything about COBRA?
