Hi Dr. Diana I checked mine that very next morning and I’m not sure if it makes a difference on what time of day you do it bc my morning one was sooo gross and thick way worse than the day before which I had done it around 5pm the 1st time and 9am the 2nd one. DRAMATICALLY different. 2nd one looked like thick snot. Ik gross right! I also checked both my daughters there’s looked similar to the photo’s in the video. I haven’t rechecked my son but I definitely will do so.. when the spit does do the nasty thing in your opinion what does that mean like what should I have my Dr check for?
