actual due date

Doc said my edd is 27 jan based on size of baby. Suddenly i hv my doubt. Since my tummy now is quite big and i've been getting frequent braxton hicks. I remembered my 1st day of last menses is 26 mar. 20th apr only spotting, 3rd may also only spotting. I started to feel different early june (nauseous and all). So if according to my last menses 26 mar, my edd shld be end dec, correct or not?
