Random spotting?

So I had random spotting yesterday. It was deff fresh as it was very pink and a little red. It's odd bc glow says that my ovulation ended Saturday and it's never happened before. It wasn't a whole lot just on the paper when I wiped twice yesterday. The only thing I can think of is the BC I took in April that I stopped after a week messed up my cycle but glow should have updated by now if figure. Anyways. Has this happened to anyone else? I was thinking on Friday and Saturday maybe my period was coming bc of the bloat I felt and the outrageous craving for ice cream. And when I spot like this I usually have my period by now. Just curious as to if anyone else has experienced this?
