I think this may be my first period since breastfeeding.. help!

ShiAnna • #1 May 2017 & Rainbow baby on the way! 🌈

Today I had BROWN spotting.. I've been cramping for like two weeks. Last time I had brown blood & cramped was implantation from my last pregnancy. What color was your blood when you got your period back? Was it heavy?

My LO is almost 4 months & ive only had sex twice.. once on the 31st & once on the 4th so I feel like it would be too early to be implantation??
