Pregnant for *what* weeks?

[Jane04]

Hi, I'm so confused on how many weeks I'm already pregnant.
I have 28 days cycle. The first day of my last menstruation was on June 23. Which makes me 7 weeks pregnant now. But I had my spotting on August1 and abdominal cramps on that week which means implantation, and that makes me about 6-12 days pregnant on that time also. So how many weeks preggy am I really?

Hi!
In obstetrics we use the last menstrual period to date the pregnancy which adds two weeks to the embryologic gestational age.  Ultrasound calculations are programmed to correspond to the lmp dates to avoid confusion.  SO, if your LMP puts you at 7 weeks, then you are 7 weeks pregnant, and your due date will be 33 weeks from now.
It's just a lot easier to go with the LMP dates!
Good luck!

Um I would guess your around 7 weeks, which means the baby is 5 weeks. Only a ultra sound can tell you exactly how far along you are. My lmp was june 30 and I am 6wks 4 days. Hope this helps :)

What if you don't know when your last period was.
