Has anyone ever got bfp's on Internet cheapies before clear blue (both their ultra early test and digital)? I'm so confused! I've been using these cheapies for about a week and never had lines like this before so don't think they're evaps... Since done another and have a third line like this. The cheapies supposedly detect 25mu but the clear blues say they detect 10 🤔🤔 should I be tentatively happy?
