I've been gone for a while

Soooo I've been gone for about 3 weeks but I'm back. I have lots of questions. My period was due October 25 didn't come until the 28th. I BD the 10th,11th,12th of that month. Since about a week before my period showed I've been having CRAZY pregnancy symptoms. Really sore and growing breast. They hurt so bad that I can't jog on the treadmill anymore without wanting to cry. I've been having a lot of discharge. Sleeping a lot but terrible insomnia at night and don't even get me started on the nausea and vomiting. Everyday I'm holding throw up or just throwing up about 4 times a day. I haven't tested because my period came. What do you think could be going on ? I wanna test but I'm scared. Made a Drs appointment but it isn't until Dec 12 ? please respond !
