Early signs vs. random pains?

Hi ladies! I have been TTC since June, and I had a chemical pregnancy in July. I am expecting AF on Dec 2. So far this month I have experienced really sensitive, full breasts...for only 2 days. Since they feel normal again, I thought it didn't mean anything, but yesterday and today I've had a weird poking/pulling sensation behind my belly button. I've been urinating way more than usual. I've done a ton (read: way too much) research on early pregnancy signs, and I don't know if these are enough to keep my hopes up. Any help is appreciated!!
