Faint Positive FRER but negative Clinical guard?

Lauren

Yesterday and today I got faint positives on First Response Early Response & First Response Rapid Result. Today I was supposed to get AF, but I haven’t yet. I had some small spotting this morning but it went away. I’ve been having light cramping every now and then.

I took a Clinical Guard test when I got home from work and it looks negative.

Has anyone had a positive First Response test, but a negative Clinical Guard?
