I've experienced pretty much the same thing twice before, both times keeping my fingers crossed that I was pregnant. Unfortunately I was not, though, and as sad as it is, I'd bet that you aren't this time either. I got funky periods and hoped they were just implantation bleeding, but it turns out that implantation bleeding is very very light in color, usually just a single SPOT and only just tinged with pink. Most woman never experience implantation bleeding either. A first response early result pregnancy test (or a Dollar Tree baby test), especially with first morning urine, would definitely pick up a positive result by this time in your cycle if you are in fact pregnant, so if you have to see it for yourself for sure, I'd suggest that.
The good news is that no matter what, there is alwaaaays next month hun! Best of luck!
