Here's my story in case it helps anyone (and also as I'm bursting to tell!) Got diarrhoea at 6dpo this month, first month of using OPKs.

Started testing at 9dpo on the off chance and got a very faint line (far right on pic). POAS regularly since then and now have the darkest line yet (far left) and period due today bit as of yet no sign.

Think that's my first BFP!!!!

Thank you SO much for the love and support on this app ladies, it's a wonderful place.

Baby dust to you all!!!
