Hi girls, Using opks as hpts has always kind of fascinated me because they are cheaper. Here are some pics. I got my BFP on the FRER at 11dpo. I had been peeing on the opks for a couple of days before because I was trying to hold off on really 'testing'. Anyway, I think it kind of answers the question that you are more likely to get a pos hpt before a pos opk as hpt.
