Need your input please!

I found out I was pregnant about 2 weeks ago. Yesterday I had a ultrasound done vaginally not by my O.B Gyn but a pregnacy center . I was so scared because my last pregnancy I had no baby in the sac and I was afraid I'll see that again.

My heart started beating fast when she zoomed in to see if she could see baby and there it was heart beat about 113 per min I was so happy she measured me about six in a half weeks!

Then she looks at me and says I'm concerned because your gestational sac is an irregular shape and I'm sorry to say but u have a high possibility of miscarriage.

I was stunned shock hurt for I have never heard of such a thing.

I have no bleeding cramping ect....

She told me to make an appt with my O.B GYN and I'm asap .

Any thoughts on this? Plz any advice will help.
