Question about due date

kljustice07 · May 2011

Hi! I just took a test last night and it was positive! So excited for baby #2! I'm having a hard time figuring out my due date and would LOVE some help. The first day of my last period was April 23rd but I used the ovulation test kits this month as well and the tests showed that I either ovulated on May 10 or 11th. Do I go by the day I ovulated or the first day of my last period? If I go by the 1st day of my last period the due date is Jan. 27th but if I go by my ovulation my due date would be Jan. 31 or February 1st. What do you guys think? Thanks so much!

I read somewhere that the day you ovulated is a better date to use but most women dont know that so they use the first day of your last period. I think your doc will use the first day of your last period, untill they do an u/s for dating. (if they do that where you go, some places dont)

Ovulation date is more accurate but your doctor will probably use your lmp. I charted so I'm using my ovulation date.

Okay thanks! I've told a few family members and one of the first questions they ask is "when are you due"? So this helps a lot!

Your doctor will go by the last day of your mentrual period - unless your u/s shows otherwise.

Congrats!

My doctor always goes by the date of my positive opk and not my lmp because I have longer cycles. I've done this for my last pregnancy and this one as well and the u/s has always confirmed the date that I calculated using my opk dates. I think it depends on the doctor .. yours may go by your lmp and then change the date once you have a dating u/s since it will likely match up to when you ovulated according to opks. I'd just tell everybody the later date since that's likely more accurate.

Your ovulation date will be the accurate date. LMP only works if you have a 28 day cycle and ovulate on day 14. As PP stated, your Doc will probably go by your LMP but when you get your first u/s you will see that your ovulation date was more accurate.

most drs will use LMP, i charted and based on my LMP and my O date my due date is in within one day of each other and as of right now my LMP date is what we're using.
