How long do symptoms of increased progesterone last if you haven't conceived?

5 days until AF and my breasts and nipples are sore/burning, I have terrible gas, nauseated, heartburn, occasional mild sharp pains just below my bellybutton, and slight cramping. Just wondering if I should be hopeful or still prepare for AF. Don't want to take hpt too early and get discouraged, but I don't normally have all of these symptoms before AF and I've never experienced the bellybutton pain before, not even sure if that's related.
