I feel like I can feel my baby kicking in my stomach. Not a lot just every now and then. I don't know how far long I am because the doctors were going off of my last period and I went for a heartbeat app and they couldn't get to the baby so there just now sending me for my 1st transvaginal ultrasound. I'm so nervous it's on Jan 4th .. I would really love to know how far along I am. It's disappointing not knowing how far along I am... ☹️
