17days til af cramps, bloating, watery pink discharge, tender breast, nausea? Pregnant?

Back to school? These are symptoms of infection, not pregnancy. And, remember it takes one to five days after sex to conceive a new baby. Then the new fetus is not in any physical or chemical way connected to the mother's body until ten to fourteen days after conception when it is big enough to have blood and chemicals to share. Thus any symptoms before a missed period are not pregnancy symptoms.
