Line progression

Jessica

Ok I may be being abit paranoid due to having an early miscarriage this time last year. First positive at 13DPO. 14 DPO positive digital on both first response and clear blue . 17 DPO today and lines have been processing Nicely on first response but not really on the clear blue I would have expected at 17 DPO for the clear blue to be super dark this morning . I know they require more HCG then first response but still at 17 dpo I expected abit more . Are these tests just not great? Please share experiences to ease my mind it’s the weekend and bloods aren’t untill next week. We’ve tried 14 months for the baby.
