Advice needed

Angie
I don't want to get my hopes up. I took a FR last night (12 dp <a href="https://glowing.com/glow-fertility-program">IUI</a>) and it was negative (top test in pic), this morning (13 dp <a href="https://glowing.com/glow-fertility-program">IUI</a>) took clear blue and it's got a slight line! But then digital is negative. Could the clear blue be throwing a false positive? Or, I'm hoping last night just was too late in the day to be testing and the digital is not as sensitive as the clear blue. Anyone have any experience with this? These are the only tests I have until I go get more...Tia
