Lochia question

🐘🐘🐘 • 👧🏼 born 1/19/16. 👼🏼 lost 9/15/17. 👼🏼 lost 11/26/17.
I'm 2weeks and five days post partum. My bleeding was very light pink/yellow for about a week, but today I stood up and noticed a gush of blood. It's bright red like a normal period and had a few small clots when I wiped... Should I call my OB? Is this normal?
