Period is a no show?

Stephany
My last period was May 30-June 3rd and as of today I'm at day 43. I'm usually very irregular as my cycles are from an average 28 days to 45 days. I did have sex with my SO on June 10th, but he pulled out (he even urinated before). I did have my 1st pelvic on Thursday and she said everything seemed normal and didn't think I was pregnant. She said if it doesn't come by day 60 to go to the doctor. I have been very stressed on the idea of pregnancy so I'm not sur wit I should worry or not?? Any advice?
