My last period was February 4th. I’ve heard to count 280 days from last period to estimate due date which puts my due date at November 23rd. Yesterday I got up felt severely dizzy and a couple hours later a big bout of nausea hit me and I just started puking.. like a lot. I thought morning sickness didn’t hit until 6 weeks or so. I’ll be a first time mom so don’t really know if that’s good or not.
