Not sure whether to test again. CD44 and no AF.

Been cramping on and off for just under a week. I have lower back pain on and off. Today I have wee-d about 20 times (but it feels like the start of a uti ) Inside my boobs (under where my nipples are, but not my actual nipples) is sore but they are not aching. I have no nausea or tiredness. I am cranky (as usual!)

I want to test but not if I get a BFN - which I almost 100% definitely will
