Doesn’t seem very dark for 13 dpo, does it? FRER was a lot darker.

Frer sensitivity is 12 mIU/ml (though some have been known to detect as low as 6.5 mIU/ml of hcg). These cassette tests have a sensitivity of 25 mIU/ml. So the frer will be darker sooner. You could also have had more diluted urine when you took the first signal. It's pretty normal.

I tested today with this very same test at 13 dpo and mine was about like yours. FRER is darker for me also. FRER is more sensitive so it will be darker from my understanding.
