Feels like somethings completely wrong 😔

My last pregnancy I had preeclampsia at the end. I gave birth in February. My BPs never really went back to normal but the stress kinda just got worse and worse. Well I just found out I’m 14 weeks pregnant... I’ve had massive headaches, blurred/spotty vision, heat flashes, and dizziness all at once two-three times. Called OB and the nurses shrug it off and state you cannot develop preeclampsia until 20 weeks - they will not schedule me for an emergency appointment. I’m scared and just have that feeling that’s something wrong.

On top of all that I’m supposed to start a new job Monday - we NEED me to work this job we are so behind in bills. So I’m scared my BP might get too high/bad that I’ll be put onto bed rest for month... so my question is if I get put on bed rest could I file for disability or unemployment? I currently live in SC.
