Hiya! So I know there are lots of posts like this but I took a preg test yesterday and got a BFN (top test on pic) this morning (second wee) I took a test presumed it would be BFN went back and it’s positive (2nd test from top) so immediately took another and I saw a shadow but left it came back 30 mins later and again feint positive …. So a took another by this point pushing the last fluid out my bladder and it’s negative (I think there would be a shadow but I live in hope ha) evaporation lines or BFP’s?
