could I be pregnant or am I tripping?!

so I started tri lo sprintec on June 24th 3rd to last day of my period the I had sex on my ovulation day which was the 6th of July and he finished in then sometime after I had started bleeding I think breakthrough bleeding july10th -13th and it was so heavy then 14th-16th I was just spotting . I had missed about 4 days maybe more but as soon as I started bleeding I took like 3 pills then continued to take my birthcontrol pills . I'm on the last week of my brithcontrol and I know since I missed so much I was suppose to throw away the pack but I thought continuing the pack might help my hormones . i honestly dont know if I even ovulate but I did have some pain the day of ovulation . Could I be pregnant?
