help! what is my due date??

[WhiteJasmineRose3]

I know that doctors go by your last menstrual cycle to estimate your due date however mine are irregular. My last cycle was on February the 3rd and I had no more periods after that I had sex on the 22nd of march that's when I got pregnant. They are using my conception date to estimate my due date however if I go by my conception date I'm only pregnant for 38 weeks not 40. I'm so confused am I due on the 12th of December or the 25th?

Your due date will be about 38 weeks from the day of conception, but you will still be considered 40 weeks because your body is preparing for a pregnancy before it happens. When you use your lmp, the two weeks are already calculated in because you usually ovulate around two weeks after your period ends.

Thank you!  Due dates can be so confusing especially for someone who has irregular cycles

Usually go by your conception date. If you know for a fact it was the 22nd of march then that was it. With my daughter I got a date of Nov 22nd then a date of Nov 31st then Nov 16th. I knew the exact date I conceived which was the 15th of Feb. By their calculator I delivered at 39 weeks on Nov 8th. She never measured big. Currently with my son, he's measuring days larger every time approx 2 or 3 days. In a few weeks we will see how much further. Either way after 35/36 weeks get ready to go.

Right now I'm 35 weeks but she's a week ahead on the ultrasound

My baby was measuring 4 weeks on April the 21st and then 4 weeks after that she was measuring at 8 weeks. What I am trying to figure out is if you go by your conception date why are you only 38 weeks pregnant and if you go by your LMP your 40 weeks? If I go by my conception date will I be expected to deliver at 38 weeks not 40?

What is your baby measuring at? December 25th sounds right if you regularly missed periods. But not having a period for over 28+ days isn't normal for everyone and can alter your ovulation cycle.
