Well after that little experiment I would day you've got your bfp! Especially if it's showing on a tesco brand because I don't think they're that sensitive. I'm losing faith in frer recently because I've seen a lot of people getting worried on here because they're lines are super faint or bfn even with bfp on other brands. Excited to see more progression pics x
I'd definitely say this is your bfp!!! I it just HAS to be!!! Xx
I really don't hun, maybe ur levels are around the 10/11 mark and just not quite high enough for Frer xxx
