AF due in 4 days but Flo app says my period is coming with a 7 day delay so who knows?! Had a CP two cycles ago and cycle length has gone from 29 days to around 40 days with ovulation around day 21! Got a BFP on FRER today (wooo!) but the IC are still so faint - I know that FRER are much more sensitive but so nervous about another CP.... do I keep doing IC to look for the darkening?! Picture for comparison from the same urine (bottom two) this morning.
