Is my cycle just being weird?

I think I ovulated around 8/1 (ewcm, high soft, open cp). 6 dpo I had a very light period that was mostly brown. This lasted until 9 dpo. On 10 dpo I had very heavy watery cm. On 11 dpo (today) I had just a little pink when I wiped and lots of cm. BFN this morning. I've been slightly crampy in and off as well. Has anyone been in a similar situation? Is it just a weird cycle this month?
