Set of eyes - worried about a chemical pregnancy

Could the third one down (first one I took today) be a dud? As of today I’m 13 DPO and I started testing on the 23rd, at 11 DPO. The one after it is much stronger so I don’t know what to think. I’ve had a chemical pregnancy before and this is my second time getting pregnant so I’m super nervous about it happening again.

Could it be a dud? Maybe I took the test with not enough urine (it was 5 AM and I didn’t have my contacts in or glasses on so it might not have gotten as much in my urine stream as I thought)? The one I took a few hours later is much more obvious. And the digital came back with a positive result too without a problem.

Thoughts please! My hubby and I want a healthy little bean so bad 🥺💖
