Implantation or just random spotting?

Bethany • Ectopic pregnancy July 2018, miscarriage January 2019, TTC our rainbow 🌈

I found out the baby had no heartbeat at 9 weeks. February 5/6 I had my miscarriage and got a negative pregnancy test by Feb. 17. I had a 10 day light period that ended March 13th and then ovulated on the 17th. I’m now 5 DPO and I’ve had increased discharge since ovulation and today it was brown and red but not heavy. It’s more like discharge than period bleeding and there’s some stretchy-ness to it. Do you think this is my body still cleaning out my system or implantation bleeding?
