Possible implantation or period?

Samantha • I have an amazing husband we have been together 7 years we have a beautiful little girl who will be 5 in April! We have been ttc since November 2014. I'm a dog groomer 😇😉😍👪💖
My period isn't supposed to start till the 26th. About 1 am it was more pink and about 8 it turned brown.
