@tripletroublemom, my due date with my daughter changed all the time too haha

first day of your last period is how they calculate it at the Dr's

I didn't have any Implantation bleeding. ..not with my first either. so I use my LMP

@jnanzer94, yea I would just go by the last normal period u had before that. that's how they told me to calculate it. cause when I first found out I thought I was around a month when I was really 2 and a half. I would just ask my doctor but sometimes there measurements are off cause babies could be big for there age or small for there age and dates are off but it's usually close. cause they still don't know my due date cause I'm carrying triplets but they know they measure at 22 weeks so anytime in November is my due date lol

I was just trying to roughly estimate how far I am lol but yeah my implantation it stopped and started again just like my period does on its own so I thought it was my period being goofy again @tripletroublemom

my periods only lasted 3 days anyway so I thought that was it

@jnanzer94, I thought my implantation bleeding was my last period also I bled for 2 days and my period was like 3 weeks before that so I thought it was my period being stupid again. but your doctor will measure your baby and can tell u about how far along you are.

I didn't think so I just thought it was my period I didn't think about how irregular it was being when I was implanting @nevahsatisfied

Implantation bleeding is not considered a period. Go by the date of your last actual period.

I thought my implantation bleeding was my period btw
