Ok so when do I go to the doctor?

I am now on cycle day 45, I looked at my previous cycles and they ranged 30-34 days. So obviously I'm late. But I have taken many tests now and they are negative. I haven't been feeling sick but I have been super tired like climb into bed when I get home tired and I seem to have the right cm for early pregnancy according to the Google. Plus I wouldn't say cravings exactly but more of a desire for specific foods. I am also super bloated. A co worker actually asked me if I was pregnant cuz apparently I have the pregnant look going on according to her. But at this point I've taken pink tests, blue tests and digital tests and nothing. So when would you go to the doctor?
