Implantation bleeding?

Desiree

So, I've recently had issues with my birth control patch this month, it fell off a few times and so I had to remove it sooner than I normally would have. I wasn't supposed to start my period until next week. I started Wednesday night/Thursday morning. Or at least I thought I did. I'm not so sure now. It's very different from how it normally is. There's barely any actual blood and for the most part it's brown and it's spotty instead of an actual flow. I was looking up implantation bleeding and it seems possible. My 'period' started about a week early, and was 11 days after my ovulation day. My husband and I have slept together twice during the past 2 weeks. My cramps are usually terrible to the point I can't do anything but sleep with my heating pad but my cramps right now have been very light. Not fun, but not intense and just uncomfortable compared to the usual stabbing. I'm not sure if it is a result or the birth control being changed early or if it might be implantation. Any thoughts?
