I am 20+ days late

Trier

I am 22 days late for my period. my last period was in June. I had sex June 25th and I'm kinda worried. should I go to my obgyn and figure out what's going on?

UPDATE

I wasn't pregnant. I went to my doctor and did a pregnancy test with them, came back negative. I'll be TTC again some time down the road.

Thanks
