Implantation bleeding ???

Hello, so i am on the pill and have been for about 3 years now. I take it mostly on time, rarely late if im busy. This weekend I went on vacation and forgot a pill on thursday, then took my friday and Sat pill, then forgot again on sunday. I’ve never missed two pills that close together, but when ive missed a pill ive never had problems.

I had sex July 21 without condom, but pulled out WAY before he finished. Then had my period as normal on July 26. And the Last time I had sex was August 2nd with a condom and took pills normal.

Now since I missed those two pills, i had cramping like my period and then brown spotting for the past 2 days. Everything i google says implantation bleeding and its starting to freak me out. Also, before this missing pill situation I kept having that feeling in the back of my head that im pregnant, this was just the cherry on top.

Is it possible that its implantation bleeding or is it because i wasnt taking my pill properly?? Ive never had a problem when Ive missed one pill. Also im waiting till my next period as well to see if i get it, but i just cant ease my mind from this. Thanks
