Or is it teeth brushing?
Anyway that was one thing that tipped me off to even test.
You see, I LOVE to brush my teeth. For reals! My DH even makes fun of me for it. But I have a track record of NOT enjoying the brushing of the teeth when I am pg. Makes me gag...iykwim.
So I noticed that I hadn't really FELT like brushing my teeth lately. I didn't enjoy it & I was even rushing to get thru it. Imagine that!
