I'm in need of some advice. I recently had an ultrasound. I was told that they were not able to see a gestational sac. I both a regular on and internal one done. According to my LMP I should be over 8 weeks pregnant. The tech at the ultrasound place says I either had an miscarriage or it's to early to see anything. I'm so confused how can I have all these pregnancy symptoms and be told this. I have 2 children already so this would be my 3rd pregnancy. Is this normal or unheard of?
