Is this an evap control line?

Question

I’ve never had the control line be so thick before from a First Response. Was taking a shower when this was processing and wondered if the heat hurt the test.

Answer

Taken 50 minutes apart. For anyone who looks for this kind of thing in the future with the glow search!! The bottom FR I took while the shower was running and I think it def messed with the result, as my doctor also confirmed my pregnancy 2 days before. I was so confused by the super thick control line as they always look thin like in the top test. Top test, it’s def there thank the Lord! I’m very early (4 weeks 2 days) and my hCg was only 14.5 two days ago so it’s consistent for being this early in my pregnancy to be this light but it is a little thicker than my previous tests and has  little more pinkness to it than the photo shows 💗

Answer

Just to update: with no symptoms at all, it’s over.

Answer

I don’t see anything

Answer

It could be a faulty test - I've never had a control line so thick on a first response and they're the only tests I use. 
Or, it could be as another poster mentioned - a chemical pregnancy.
Or it could be that your hcg level was diluted - especially likely if you're not using first morning pee,
I'd retest with another first response and first morning pee.

Answer

2 days ago - the day the doctor confirmed.
