So scared...

Ch
I had my first ultrasound at 5 weeks and they couldn't see anything. Made me come back in 3 weeks which was today. My uterus is turned and because of that they couldn't see much. Had to do a vaginal ultrasound and first they thought it was an empty sack. Then they zoomed in and saw two beans but no heartbeat. After a little bit it looked like one of them had a heartbeat but it wasn't very clear. It also measured 6,5 weeks where I believe I'm 8. The second bean could also been the yolk sac but because of the angle of my uterus it is really hard to tell. Have to go back in 2 weeks again. This is my first pregnancy and I am so scared now... I felt so positive this morning and now I can't stop crying.......
