Possible pregnancy question AF is always regular roughly 6

Patient: Possible pregnancy question.AF is always regular roughly 6 days no less, heavy & painful. In april it came 5th and ended 10 th/11th. Period calculator apps told me may was due on the 5th. But this time it came on the 1st (no cramping) light amd only lasted 3 days. I have been moody for weeks, have bad diarreah for weeks now, back aches, my vagina feels wet and my tummy feels very funny but not cramping. My partner have been actively trying. Now my apps tells me I was due either on the 27th of may or tomorrow. Im so confused but afraid to test in fear of disapointment?
