I just got a positive pregnancy test, but I'm not sure how to calculate my due date or how far along I am. How can I accurately know how many weeks into my pregnancy I am?
Just download any pregnancy tracker app and enter the date of your last period (LMP). It will instantly calculate your weeks and due date! However, the dating ultrasound scan is the final word.
Doctors always calculate it from the first day of your last period. Since I had thyroid issues, I was very careful with my dates and doctor visits. Your gynac will do a dating scan around 7-8 weeks which gives the most accurate gestational age.
I was so confused about this because my ovulation was late and the app dates didn't match! But don't panic if your dates seem off. Your doctor's ultrasound scan will give you the correct week, it is very normal.
Oh, I spent hours calculating this online and got so anxious because my cycles were irregular! It is calculated from your last period, but please don't stress over the math. Just let the doctor confirm it with a scan.
Medically, your pregnancy is calculated from the first day of your last menstrual cycle (LMP). But honestly, the dating scan done in the first trimester is the most accurate way. Just visit your doctor and they will tell you exactly.
