Please give me your thoughts.

So here's a long story. 
My periods were coming about 2.5 weeks apart and very very painful. This happened about 3 times before I was like this is it. I'm making a doctors appointment. 
So. I had protected  sex on the13th of June, he didn't even finish inside of me, regardless of condom. I got my period as predicted in the 21st of June and it ended on the 27th. 
My doctors appointment was scheduled for the 22nd of July. But I was suppose to get my period the 19th. 
Day of my appointment I still haven't started, my doctor didn't my pap scan and pelvic exam and I told her I was late. So she had me pee in a cup. The result came back negative. 
As the weeks passed I still didn't get my period. So towards the end of July I took two test and they both came back negative. I put it to rest until now August when I was suppose to get my period on the 16th and I still haven't gotten my period. I went and bought another test and it came back negative. I will take anther one in the morning. 
So according to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> I'm 33 days late. 
What am I suppose to do? Or think? I keep reading online about how people are pregnant regardless of their test results. I do not want to be pregnant. 
I feel like sometimes I get cramps and I'll be fixing to start but I don't. I haven't had sex since the 13th of June because I don't want that to risk my period not starting. What do y'all think ?
