I agree 100% with Trying.
You may just have to rack up some more ER bills..it's either that or put you and baby's health at risk. You NEED to get some IV fluids and nausea medicine, and you need to do it TODAY. So if you can't get in with an OB because of insurance issues, your only option would be to go to the ER.
I don't think you have many options here...you must be seen. I'm sorry, I know medical bills are horrible but much better that than risk baby's health and your own. When you're there, ask them to refer you to an OB or GP who will see you on payment plan or pro bono until you get your insurance sorted out...you cannot continue like this sweetie, it's not healthy.
If you dehydrate and are pregnant you can go into preterm labor. Dehydration causes contractions and u could lose ur baby if its not treated. Please see a dr. Good luck.
