Maybe I’m being crazy

But I just got done with AF. It seemed normal, heavy one day and then light the rest. But today, I’m feeling so nauseous so I decided to take a test. The first response doesn’t really look like much, but I think I see something on the Walmart cheapie? Maybe I’m crazy and no one else sees it lol. I mean I’ve heard of people having heavy implantation bleeding before but I don’t know... what do you guys think? Any experience with this?
