Irregular gestational sac

Cynthia • 29 years old. Baby #4 on its way...13 year old girl a 10 year old boy and a 6 month old baby girl.
Hi everyone... So yesterday I went into my drs. I was having some sharp pain on my left side lower abdomen....almost front hip area. Well they did 2 ultrasounds. One in the drs office and one with the ultrasound tech. I got to see the heartbeat and there was a fetal pole....my Dr said she was concerned because my gestational sac was irregular. I guess it was supposed to be round and mine was kinda rippled for the first ultrasound and jelly bean looking during the second. My hcg levels are normal. I'm sick off my butt. No bleeding or spotting. And I'm waiting to hear what is going on. She did say she thinks I have a cyst or a pseduosac with a tubal pregnancy but wasn't for sure. I'm so confused and worried. Anyone else go through something similar? I'm supposed to be 6 weeks 6 days according to LMP but she measured me yesterday at 6 weeks 1 day.
