Line progression

[Herb1978]

Are test strips any good? Mine have been very faint lines however yesterday's was taken after holding wee for 4 hours, today's was 8 hours and today's is definitely lighter. I took FRER's at same time and I think it looks darker today.

Should I be concerned about the lighter test strip?

Your frers are certainly progressing which is positive. I'm having the same issue with test strips at the moment which is making me paranoid about a chemical. Perhaps just too early to properly track progression with a cheapy? Fingers crossed for both of us 🤞
