My period recently ended but during my period little bubbles were in my blood. (not blood clots) but noticeable bubbles.. Now today since my period has ended just a few moments ago I went to the restroom and notice the same bubbles in my discharge.. i’ve noticed a thin line of blood.. any help or advice ?

But my lower stomach will like growl i’m not cramping or anything, i don’t have a fever or feel sick.. i’m perfectly fine. just the discharge is worrying me ..
