What's going on?

🌸🦋
Last night, i stuck a finger in me to see if i would get my period, i swiped to see blood mixed with cm, really light blood so i thought AF would be arriving overnight . This morning, i did the same thing and nothing except a lot of cm. and no blood, just a lot of discharge on my underwear. Been going to the bathroom all day and still no blood. My period is a day late & i'm not cramping as I would, i usually have bad cramping, and i have sore nips, but no period .. What do you think?
