Thanks. It would break my heart if I was pregnant by someone else .
If you count back it looks like you conceived around 12/24 when you were ovulating after your period went off. If you go to babymed.com and enter your due date it will give you your conception date.
I usually start on the 3 but I was 3 day's late an I started on the 6 not heavy but it lasted 3days on an off.
Well, if you had your period in December then nothing happened with your November mishaps. It's after your period in Dec when you concieved.
