Am i Pregnant??

[Twin Sister]

I hope everything went well with your ultrasound!

I had my ultrasound done the day before and had a little talk with my doc. She says that my last scan(aug 28th) showed an empty yolk sac and my 2nd scan showed baby with the heart beat but the heart beat is a bit low(it is 102 but 120 is normal itseems). She adviced me to come down to her office to check my uterus size and repeat the harmone test and ultrasound again in a week. She says if progestrone level is low she would prescribe some medication but she doesn't give that guarantee that if i take the medication everything would be fine. She says she has seen a few cases like this which showed low heart beat but the heartbeat picked up later. She is not sure which way I am going.

Im totally in a dilema...Im not sure how many weeks pregnant i am and also if a heartbeat of 102 is normal. Can i do something to improve my condition? Im a victim of sleep apnea.Does this effect my pregnancy? Im not sure if this is helpful but i found this info on my ultrasound report.
EV7 26hz
7.0MHz 30mm
EV

PWR= -3 db

Someone please help me to know what Im going thru.

Thanks...
