should i get a midwife?

in my previous pregnancy i had concerns and i called the doctors office telling them i had pelvic pain for over an hour and liquid discharge. they told me to just take a tylenol and drink water, but when i told my mom, she said no i need to go to the emergency room right away (she’s not a nurse or doc). i went and it turned out my baby was coming out 20 weeks early and i ended up losing him. now i’m pregnant again but i don’t feel comfortable calling the doctor’s office if i have a concern, is there a hotline # i can call instead, or someone else i can call for pregnancy advice?
