My periods are always irregular so im not sure of the dates at all. Doc told one week but my own counting says different. How do u figure out the exact week na?

My brain was so foggy I couldn't even calculate my age let alone weeks, lol. I just looked at the top corner of my latest ultrasound report where they print the exact week and days!

I just had my baby last month! Your dating scan done around 8-10 weeks gives the most accurate gestational age, even if your LMP date is a bit off due to irregular cycles.

Don't stress too much about the exact days dear. Your doctor will tell you the correct week during your first dating scan, just focus on resting.

The easiest way is to calculate from the first day of your last period (LMP). You can just use an online pregnancy wheel calculator on your phone, takes literally 2 minutes.

The dating scan will give you the exact week. Knowing this is so important, especially if you have to track sugar tests and diet plans at specific weeks like I had to do.

Chithra Gandhi · Answer

Just download any good pregnancy tracker app like Flo or BabyCenter and enter your LMP date. It gives you the exact week and daily updates, very straightforward.

Honestly, I am in my 3rd trimester and I still get confused counting weeks vs months, haha! Your ultrasound report is the only reliable thing that tells the exact week because baby's size doesn't lie.
