Hi, I've been seeing very small amount of blood whenever I spit out toothpaste after brushing my teeth. The blood isn't exactly dissolved in the spit. And the thing is my gums are perfectly fine. On seeing in the mirror I don't see any blood around my gums or teeth either. There are no ulcers in my mouth either. So, I was wondering what could've been causing this? Also I was diagnosed with gastritis a year back, so maybe the blood is coming from an ulcer in the stomach? Also it only appears when I brush my teeth after waking up from sleep, usually in the mornings.
I've been stressing over this for a while now, please help me!
