Can someone shed some light?

Elysia • Baby girl born Feb 2019!! 👶💖 followed by 3 angel babies 👼

So I’m currently CD13 and normally have a 32-33 day cycle so am not yet in my fertile window, since last night I have had a really stabbing and squeezing pain in my right pelvis and then at lunch lots of creamy cm with a streak of brown and then this evening more brown streaks,

I’ve never had a cycle shorter than these days and never experienced any spotting mid cycle....

Any suggestions?
