5 days late?! What’s going on?

Hey ladies! I’m 5-6 days late. I had CM for the past 2-3 days and I thought hmmm? Hubby and I baby danced on those days and I read online that if a man ejaculates inside of you your body cleans itself by removing the extra sperm left inside with your usual vagina discharge. (Something like that) but I also heard it could be a sign that your menses is coming or early preg symptom. I don’t have tender/sensitive breast, I don’t use the bathroom more often, or have back pain. I have nausea here and there and cramping and a pulling sensation on my right pelvic area one time for like 3 mins yesterday and so I thought AF might be on her way, but Nothing! I took some cheapie preg tests over the past few days, all negative. I gained weight super fast this month in my belly area. But to be truly honest I don’t feel anything weird. It’s like I don’t feel like AF is coming and I dont feel I’m pregnant. Is this just a late AF?! Any advice?
