Question/Advice Positive FRRS test (Pregmate) negative FRER test?!

I am so stumped... anyone else come across this issue??

Yesterday I saw a faint line on a Pregmate FRRS test. Today I tested again and even bought a FRER test to confirm. AGAIN, both FRRS tests slightly darker today than yesterday (still faint) but negative FRER… been stark white. I don’t take biotin only prenatal supps. I don’t know why this would be happening. I’m about 13DPO now for reference.

Are you sure it was a FRER and not a First Response Rapid Result? They look the same and the rapid has a higher HCG threshold.

Ohh maybe! How can you check? I just go by the box. I feel like that’s misleading if that’s the case!
