okay so on sep.15.2009 I found out I was 2 days pregnant.
Do you mean at that point you were 2 days late?
I had my last period on the 26 or 27.
The first day or the last day of your period?
I had sex with my ex. Two times on like the 30 and the 1. but then the rest of the time I had sex with my boyfriend. Does it really take a week for the baby to develop?
I think you mean a week for the baby to
implant. Meaning the egg is fertilized and approximately 7 - 10 days later, it implants in your uterus. That is when you might start to experience symptoms and have a positive pregnancy test.
Pregnancy is counted from the first day of your last menstral period. So, being 2 days pregnant, probably makes you 3.5 - 4 weeks pregnant.
Sex APPROXIMATLEY 2.5 - 1.5 weeks before your period is probably when you conceived.
and is this baby my boyfriends?
Honestly, only a DNA test will tell you. Sperm can live inside your body for up to 5 days.
