Implantation bleeding? Pic included

Had sex on February 3rd (unsure of when I exactly ovulate) & it was unprotected. Friday, February 9th I had brown discharge that lasted half a day. I’ve never had discharge between periods. So I’m thinking okay this must be ovulation bleeding. Then on Monday, February 12th I went to wipe & it was pink discharge. & it only happened two wipes & never saw it again.

I’ve taken two pregnancy tests since then & both been negative. I start my period February 22nd.

Only things that have been happening is that I’m extremely congested but so has the people I’ve been around. Bloating really bad. Feel like a sitting nausea that goes away after I burp. & yesterday I was sitting in the car & all of the sudden my stomach started to get really warm like heat was radiating off my stomach & then my boobs did the same thing.

Anyone have any thoughts?!?

First picture is with the brownish/beige discharge, the picture was taken & never saw that discharge again so it was at the end. The 2nd pic was the pink discharge on Monday.
