Equate early response

There a visible line that I assuming is an indent. I’m only 8 dpo and can’t see any realm where I would have a line there this early. I switched from first response early result due to indents and it looks like I’ll have to switch back. Any recommendation on test will be greatly appreciated.

Did some further research and heard equate gives off indents. I’m having a Killer migraine so if it’s not better by tomorrow I’m taking a test then taking some motrin. It’s the only thing that helps with hormonal headaches.
