Tmi very sorry.

Ok I really don't wanna ask this but I need help cause I'm not really sure y this is going on an it has never happened to me before at all. On so my period isn't due till the 28th an on the 21st I was checking my cm an noticed some creamy like discharge with a little blood in it an that was about 3pm,an then nothing else till the 22nd about 5 pm again when I was checking my cm. I have been doing some spotting since the 22nd but it don't come out an the only way that I even see it is if I insert my finger an that's it. Other wise it don't even come out on the baby wipes. So what I am saying is I wouldn't even notice this if I didn't insert a finger. Yes tmi I know. Just need a little help cause like I said this has never happened to me at all. Also it's not every time either it's off an on an I may only see it maybe three times a day an that's it. So very confused.
