Am I nuts or sane?

So the last couple of days has been a little off to me. First the fatigue I mean really, really tired like i slept until 1pm the other day and that is not at all like me. Then for two days straight my cm was OFF THE CHAIN. I mean I thought my period had came on, it was soo much. Then my 4 year old son has been my shadow a lot lately. He is usually independent with a small amount of clinginess then him and his brother is stuck on YouTube for hours. But lately he has been coming laying all under me until he just passes out. I tell him to go to bed and he just says mommy I want to be with you. Now my body has this feeling of "uncomfortableness". I am bloated and my pouch or pooch has this slight heavy feeling. Af is not due until around the 16 of October and just left September 25. Opinions help am I acting crazy or is this a sign??
