Is this implantation bleeding ?

My last fertile day according to Ovia (which I used for my first pregnancy ) was May 31st my husband and I had intercourse , and it’s now June 2 and I had this happen. Its not a lot.

My period isn’t due for acouple more weeks.

Did this happen to any of you ladies ? When does implantation bleeding happen ? I felt super sluggish and nauseous today. I’m hoping I’m pregnant , I feel like I’m going to be.
