Brown spotting after first period?

Holly • 24 Mama and Wife ❤️

So I had my baby on Dec 17th. I stopped bleeding at 5.5 weeks. And then I had my first period lasting from Feb 2nd - Feb 8th. It was a rather normal period, but just a little heavier than ones I had in the past. On the morning of Feb 14th, there was quite a bit of brown blood in my underwear. Like, more than "spotting" but not a ton. I put a pad on and throughout the day, I just spotted. Now it is the end of the day on Feb 15th and the spotting is still going. Is this normal? This has never happened to me before, so I dont really know what it means. I know that brown blood is just old blood, I just wasn't sure why it was occurring now or if it meant anything.
