Light blood and brown discharge

Brittany

So I’m having light blood and brown discharge. This has been going on for a week now. It’s not all the time just periodically through out the day. We are TTC so hoping it’s implementation bleeding but I’ve had this type of discharge before but not for like two weeks. It started right after my ovulated like a day or two later as of today my next period is in 5 day. What are your opinions? Period or implantation possibility?
