Pregnancy talk

I am currently 23 weeks an 6 days but the past couple days, and nights I been feeling pain in my lower belly an like on the top of my vagina. I’m kinda new to this due to having a early miscarriage 3 years ago, but I’m kinda nervous to talk to anyone an my mom said she don’t know. Could anyone help or should I suck it up an call, and talk to a doctor about it? I have a appointment on Wednesday to.
