Am I pregnant?

Okay guys this might be long but I want to give as much info as I can to know what to do. So this is my first month TTC. I got off birth control in June. I was on Nuva Ring so I always had regular periods. I was supposed to get my period this month on the 20th I took a test a day or two before my period was due and it was negative so I was just waiting for my period to start and now as of today I'm 5 days late. I took another test yesterday and it's still negative. I also have had some symptoms like nausea, cramping, fatigue but they could also be PMS symptoms. I also know cycles can be anywhere from 21-35 days long & according to my last period today would be day 34. My normal cycles are usually 28 days long. The first day of my last period was July 23. So that's it what do you guys think could I be pregnant? Should I get a blood test or just wait? Thanks in advance for your advice. 😄
