Driving myself crazy 🤪 eyes and advice needed please

I’m late for AF not 100% when I ovulated and have had sore boobs for day or so! I’ve had a very very faint line on a cheap strip test, next day followed by a BFN so I finally got hold of a first response test and did it this afternoon - this is what I got...

So could this be a BFP on its way or the fading of a chemical pregnancy? Or even just an indent? Pic taken at 3 minute mark! I’m driving myself crazy with the ‘is it, isn’t it’ type questions 🧐 I will retest tomorrow with FMU and keep everything crossed 🤞

***update***

After being 4 days late and two positive (faint lines) I’ve started bleeding and cramping today, so I’m thinking this was a chemical pregnancy 😔
