Postpartum periods

I had my first postpartum period from June 4th - 7th and today when I went to the bathroom this evening I had light pink light bleeding. Is it normal to have your second period 2 weeks later? I’m trying to figure out if I need to go into the hospital and of course the clinic & urgent care are already closed for the weekend. 😫 I have a blood clot in a vessel in my brain that I’m on Warfarin for & I was a nervous reck during my first period due to the potential of increased bleeding.
