Help!! Where is AF!!?

Joanne
 Now 10days late for AF. I took a test 9 days ago and got a VVVF positive (see first pic) I retested 2 days after and got a BFN. I've tried to put it to the back of my mind but I keep getting strange sensations in my lower stomach, kind of like a fluttering and I'm constantly tired. I've re-tested this evening (see second pic)  nd I'm not sure if im seeing the start of a VVVF line or if I'm finally losing the plot!! Please can I have opinions...
