Ovulated later than expected, pink spotting? Help me please.

Gi

I had stretchy CM starting on the July 24. Then I had it again July 31 on. I thought I ovulated earlier with the first stretchy CM, but my chart is saying I ovulated later than I thought with the second stretchy CM. I had some tiny pink blood when I wiped lastnight (5-6 DPO). Could it be possible I'm pregnant based on the CM, pink spotting, and BBT?? [My temps were jacked up earlier possibly because I'm 7-8 months postpartum]. Thank you.
