Mother’s intuition or just wishful thinking....

I am currently 34 weeks +5 days, myself and baby have consistently measured 2 weeks ahead from the beginning of my pregnancy (I think my due date is wrong due to me having severe PCOS and my periods being out of wack) for the past week or so I have had the absolute worst pelvic bone pain and it feels like my pelvis is about to break in half. I have been having the worst back pain, as well as consistent Braxton hicks...I know these are normal 3rd trimester pains but I have felt my whole pregnancy that I won’t make it to my due date, have any other mommas just known they would have their baby early in this pregnancy or a past pregnancy and you really did have them early??
