Yes, I am really asking this...

I feel like it's so cliche to come into a women's forum and ask perfect strangers if one might be pregnant following a list of arguable signs. However. I am just hoping someone may have had an experience similar to mine, just to calm my nerves, not give me a diagnosis. So, with all that said, allow me to explain. I started Ortho Evra (the patch) on the 17th of April, which was the last day of my period. I had sex April 22,23,24,25,26,27 sometimes with a condom, but mostly not. According to Glow, this was during my ovulation. I took the patch off on the 24th (so I used it for about a week only) because I changed my mind about using it. Don't ask, lol. Anyways, now it's the 30th and I have just started lightly bleeding. My period isn't due until the 10th of May, but I am wondering if that week of hormones threw it off and caused early breakthrough bleeding or if this is implantation. I understand there is no way to tell until I take a test, but anyone have any ideas? I would really appreciate it!
