41 days late with negative results..help

I'm not sure where to post (kind of new). My first day of last cycle was july 11th and I've taken the urine tests and a blood test, but all negative. Last month i was feeling nausead all the time along with other symptoms, so i thought i was for sure prego. My family Dr said maybe thyroid but i had it checked 6 months ago and fine. Is it time to go see an OBGYN? Im just nervous about atypical pregnancy or if something is wrong. It's stressing me out more when thinking about it. 😕 my husband keeps telling me to not worry and get stress-free but easier said than done. We got married in June so of course I'm being questioned all the time if we are trying or if I'm pregnant yet, ugh
