Since you conceived mar 18. Minus 14 days so I would put in March 4 as my last period and that would give you a better idea of a due date. IF THEY ARE RIGHT ABOUT YOU CONCEIVING MARCH 18.
My due date is december 10th i my dr told me everything is adding up.correctly and that i conceived march 19th. My last period was March 5th. I hope this helps!!!!!
Yhu can have a period while pregnant not sonething yhu see evryday but it can happen.......
Technically the first day of my last period was feb 20. I conceived march 18 (my ovulation dates dont follow the "normal" days) so even going by last period it would put me with a nov due date and not a late dec due date. I dont understand why they are using the bleeding i had AFTER conception as a "period" since you cant have a period and be pregnant.
Hmm. Oh well. Either way ive only got about a month left.
They go by the first day of ur last period. That means ur conception date is 2 weeks later. So add 14 days to that
My last period was March 7 my conception date is the 21 of March my expected due date is December 12...hopefully this helps a little
