Hi lovelies. I have PCOS so my cycles are irregular / sometimes absent. My last period was 17th May, and I've only been doing OPK's for the past week or so all showing negative. So I have no idea how many DPO I really am, or when my period is due. I've done a First Reponse this evening (stupid I know, I have 1 left for my FMU tomorrow) but I am sure I can see a line. I'll post the original pic & also a tweaked one from the checker app. First Response says to check results any time from the 3 minute mark, and never after 10 mins, these pics are from 4 minutes from testing. Trying to get some second opinions, what do you think? Xx
