What is lmp date in pregnancy?

Question

My doctor asked me for my LMP date, and I'm a little confused about what exactly it refers to. Can someone explain what LMP date means in terms of pregnancy calculation?

My LMP due date and my ultrasound due date have a 6-day gap. Did anyone else face this? It makes me a bit anxious.

Meena Pai · Answer

Your LMP is the first day of your last period, but always let your gynac confirm the final due date using the early dating scan.

I was so stressed out trying to figure out these calculations early on! It just means the day your last period started, so take it easy.

Anshu Deshpande · Answer

So does that mean the pregnancy weeks are calculated even before conception actually happens? That is so interesting.

Monika Rane · Answer

LMP is your Last Menstrual Period. It means the very first day of your last period, and apps use this date to calculate your estimated due date.

Knowing your exact LMP is very helpful for the doctor to track early fetal growth. Make sure to note down the date clearly for your first scan.

Anshu Das · Answer

It simply refers to the first day of your last period, dear. I totally understand how all these terms can feel so confusing in the beginning!

Bharati Doshi · Answer

Since I had irregular periods, my LMP wasn't accurate for calculating weeks. My doctor corrected my due date based on the scan, so do consult your gynac.

Anshu Das · Answer

Beta, it is just the first day of your last monthly cycle. Eat healthy, drink warm milk at night, and let the doctor do the calculations.

Basically, it is the day the whole roller-coaster ride officially started! It's just the start date of your last cycle before u missed.
