I Am A 45 YO Female That's 17 Days Late.

I am a 45 YO female that's 17 days late. I took a pregnancy test 2 days after my missed period that came back positive. As I've have a number of miscarries in the past I don't have the same symptoms I had in the past and I don't feel pregnancy, should I see my regular OBGYN to see if I may be experiencing perimemopause?
