No fetal pole at 6weeks 2 days yet...

Vanessa
So I went to the doctor and my dates where off. I was about 2 weeks earlier than expected. I went for my ultra sound and they seen the gestational sac and yolk sac and no fetal pole. I found out I was pregnant at almost 3 weeks! I've been doing some research online and alot of women say they had the same thing... they went back and the baby was there... has anyone else went through this? I go back next Monday for an ultrasound. I pray everything is OK. But from now till then... I'm a mess. I have an 11 year old daughter and I lost twin boys February 1 2015. My heart can't take a pain like that again. Ladies... help please!!!
