Implantation Bleeding?

TMI but I need some help with this. Have any of you ladies had this while you were pregnant? I’m just wondering if it’s a sign of pregnancy. This will be the second day with this happening to me. Glow says I ovulated on March 1 but I’m thinking I ovulated much later then that. AF never made her visit last month and still hasn’t made an appearance. I know this isn’t my period coming. Any information will be very helpful
