Anxiety while pregnant??

Since this pregnancy my anxiety has been through the roof when it wasn’t before I was pregnant and I’ve debated asking my ob if there’s anything I can take for cause it’s getting almost unbearable. I’m worried though that it’s too late to ask because I’m almost in the third trimester. Anyone else need to be put on anxiety medicine while pregnant and how far along were you when you did?? Please any help would be great 😩
