how do you know how far along you are?

I think my last period was june 11 am i 4 weeks? I think i conceived on June 26? Anyway, i am confused...what else is new.

thanks:)

Start counting weeks from the first day of your last period.

I have you at 5w1d.

I had the same question when I first found out.  Here are the great responses that I received:  How did you or your doctor determine your due date?.

Most doctors calculate your weeks by the start date of your last period.  Did you period start on June 11th?

yeah, but you didn't conceive on the start date of your last period.  that's the beginning of your cycle: you ovulate around the middle of your cycle.  so if your period started on june 11th, and if your cycle is 28 days, you probably conceived within two or three days of the 25th.

so, yes, your guess of june 26th is probably dead on.  which means you're 3 weeks along today.  just 37 more to go!  congratulations!

You add one week to the date of the first day of your last menstral period, then subtract 3 months, this is your due date. You can figure from then what you are week wise. Or go to a pregnancy website and you can plug in the numbers and whoola! They'll give it all to ya!

Your baby will be born on or around Wednesday, March 18, 2009.

You are about 5 weeks pregnant.

Your FETAL AGE is 3 weeks, but you are 5 weeks pregnant. Confusing, but most everyone I know says how pregnant they are not the fetal age. For example, I am 19 weeks pregnant, but my fetal age is 17 weeks. Clear as mud?!?

Yes I got 3 weeks Fetal also....I don't know about anything else....I just counted from your 1st day of your last period, then counted to 14, which took me to June 24th, and figured from there....... 

Go to the doctor!!! LOL! Also, congratulations.
