7 days late period, white creamy discharge

Like what it says on the subject, my period is been late for 7 days now, I’ve been having on and off cramps, my boobs are been sore for two weeks now,the first week is painful but today not much, and my CM is been creamy but today i have tiny cramping and I felt wet down there and when I went to the restroom and touched it, its bunch of white creamy cm. And oh, I almost forgot, I’ve been having heartburn, I’m not sure if it’s really heartburn but my stomach feels hot inside and it feels like my stomach is empty when I just ate..I’ll be testing maybe this weekend..and also I’ve been feeling tired this couple of weeks, I’ve been going to been by 8:30pm.
