Positive, late period, negatives?

Catie

I got a faint positive last week. My period is now 2 days late but I haven’t gotten another positive. I have NO symptoms other than mild back pain and usually I’m raging with all the symptoms. I feel like I’m pregnant but then I keep getting negatives. What’s going on?? This was my test from a few days ago. (The tests I use have great reviews and no documented false positives)
