It is possible either way...however I am due on the 29th also and they say i conceived on November 6th...good luck!
Your conception date would be at the start of november but your safe bet would be to do a dna test if your not sure good luck
With my first pregnancy I knew it was my husband and they changed the due date 3 times!!
Plus I conceived around October 27th this year with my second and im due July 17th.hope that helps
Thank you. My lmp was sep 28th
