positive opk

Roslyn • Currently mummy to 3 beautiful girls currently ttc rainbow baby 👶🏻🌈🌈🌈👶🏻 x after 9 months of ttc our rainbow 🌈 baby is cooking away nicely due April 9 th god is great ❤❤❤
Can anyone tell me when u get your positive opk which was this morning the best times from now to get busy and I am a little confused as glow has predicted my most fertile day this Friday coming can your ovulation dates get mixed up after a miscarriage and d and c ?????? Or will it be a false reading ?
