I lost mine on my first and then ignored it cause I was told there should be blood in it and mine was clear.

I've been having same and no blood in it.
It only has blood if one of the blood vessels in your cervix breaks. Some times they don't, I haven't had any blood in mine and mine keeps regenerating and then coming out. It sound like your mucus plug to me.
Not all mucus plug has blood in it, sometimes it has blood in it other times it can be pinkish, or just white clear.
