Sex, Birth Control, & periods.

I was on the shot May 8th 2017. I got my period May 6th but my doctors office was closed so I had to wait until Monday to get it. I bled everyday of the three months until I was due for the next shot, but my doctor didn't recommend. So I was out on the pill and a few days after taking it the blessing stopped. I had sex July 28th, and 29th unprotected but he pulled out, and I was on two forms a birth control basically. This week I'm stating the white pills ok my birth control, and I'm suppose to get my period one of the six days from the 20th-26th. I took a pregnancy test the 15th and it came out negative. I don't have any symptoms of early pregnancy but I don't have any normal symptoms of my period coming like I usually do such as a Back ache and cramps here and there. I just want some opinions if you think I'm pregnant or not. I don't feel I am but it's nice to have other read my story and give me feedback.
