Question about my situation?

Megan
So this month, I was worried cuz my withdrawal bleed came a few hours later than usual. I was extremely stressed so I assumed that pushed it back. But I was also for some reason worried I was pregnant even though I take the pill around the same time everyday and I've never missed one, and my boyfriend and I use condoms too anyway.
The last time we even had sex was the month before and I had another withdrawal bleed since then. Besides that, this month we had only done oral and manual sex.
Since my withdrawal bleed was "late" in my eyes I wanted to take a test to ease my mind. The test turned out a clear negative, but as the dye was running through the test window it looked like it flashed a line before it turned negative. That's still negative right? Since the dye didn't stick?
I got my withdrawal bleed a couple hours after I took the test, and im about to start my next pack of pills.
Do you guys think I'm fine and not pregnant? For some reason I keep worrying about it even though I got my "period", took a negative test, and we hadn't had sex in awhile.
