Hi everyone!

I am new to the forum its my first time posting.

I have my period regularly every month, one day less or more. However, for at least 6 months now my period starts as usual heavy for 3 days, then lighter with brown discharge. Brown discharge stops after the 5th-6th day, then on the 8th day I have light pink discharge which lasts for about 2 days...Any idea what this could mean? I am 28 and exercise almost everyday, I dont know if that can affect it.

Thank you all I am freaking out it never happened to me before
