Period lasting weeks

I hope this is the right forum. I had my baby 2 years ago and breastfeed until   My little was 18 months old (January). March I got my first period after having baby, it was normal. Then again in April, normal. But May's period has yet to end. Started the 21st and hasn't gone away. It's not heavy, very spotting. I'll go almost a whole day "dry" and then all of a sudden it comes back. Any advice or help would be greatly appreciated! Thanks
