Help me understand this.

So about a week ago I took a test since I was 7 days late and it showed a faint positive. So at this point I figured I’d wait a few days and test again to ensure the line got darker before schedule an appointment with the doctor. Over the last several days I’ve been feeling extremely tired as I did with my first pregnancy and had noticed some changes in my appetite as well being very emotional which is not normal for me at all. Fast forward to this morning I took another test and it was a bfn! I’m now 11 days late and no sign of aunt flow anywhere. What happened? Was it a false positive? Am I going to miscarry?? I’m so confused and heartbroken as we’ve been trying for a yr to have a baby and this is the first time I’ve got anything more then a bfn! Pics below of the first test as well as the from this morning
