Avoiding pregnancy. Got my period late.

I didn't have sex with my partner. We made out. He fingered me and came between my breasts. We instantly wiped it out. I had my jeans & underwear on. We dry humped. He didn't have clothes on. He says that while he was fingering me, his hands were completely clean. The date was 24th June. I am not very regular with my periods but I remember it was the time as I started having cramps few days before 24th June. I got my periods on 26th June in the morning. It was normal 4 days period like my usual ones. It didn't look anything like implantation bleeding. Ended on 30th June I guess. Then I got my next period today on 22nd August. It should have came near 30th July but It didn't. Also, I don't exactly know days of my cycle. It's irregular sometimes. I also have fever because I lately had cold drinks. Tonsillitis & I'm feverish. I have also done 2 pregnancy tests on 16th Aug. 1 I did in the night at 12:16 am & 2nd in the morning at 5:30 am. Both were negative. Am i pregnant ?
