What's going on with my body?!

Kendra • Wife and mother❤
I'm now 5 days over my normal period lenth. Wich has never happened before! The whole time (11 days) its been light red/pink, thin with no blood clots. I took a pregnancy test a week or two ago and was negative. I have had 3 confirmed miscarriages, possibly more unconfirmed and I know this isn't it. What could it be? *this is thr first time iv had a period since the last miscarriage. But I had light but kinda normal periods after the first two miscarriages. *all miscarriages were around 5-7 weeks.
