Thinking this might be a chemical pregnancy?

Megan

Took a test today- one day before my period. I’m pretty sure there is a line but super faint. I had a bit of bleeding a few days ago (started 7 dpo) which could have been implantation or from a gyn exam that I had a few days prior. But this line is so faint so I’m thinking it’s gonna be a chemical. I had a similar experience in March where I got a clear positive followed by my

Period. Thoughts?
