I just found out I'm pregnant and I'm so excited! How do doctors calculate the due date for pregnancy? I want to figure out approximately when my baby will arrive.
Oh, I used to panic because my app due date and scan due dates were different by a week! But my gynac explained it's completely normal as baby growth varies. Just count 280 days from your last period's start date as a rough guide.
Your doctor will give you an estimated due date based on your first dating scan, which is usually the most accurate. I ended up having a planned C-section a week before my due date anyway. Just trust your gynac's timeline.
For naturally conceived pregnancies, doctors calculate from the first day of your last period, but for IVF, we calculate from the embryo transfer date. Please don't worry about the exact day, babies rarely arrive on their actual due date anyway. Wishing you a very smooth journey ahead.
Usually, the doctor calculates it using your last menstrual period, but the baby will decide their own birthday. My little one arrived 5 days after the due date when I was least expecting it. Just focus on resting and preparing for your sweet baby.
You basically add 9 months and 7 days to the first day of your last period, though honestly at this point in my 3rd trimester, the due date feels like a lifetime away! Just get ready to be tired of waiting, haha.
