Successful pregnancies with irregular gestational sac

Hi ladies, I am 6W5D today and nervous as hell regarding my US in 2 days. At 4W the doctor said I have an irregular gestational sac and will let nature run its course. So far I haven’t had any cramping or spotting. I don’t have too many symptoms either, just nausea and sore breasts on and off.

Please share any successful pregnancy outcomes with irregular sac diagnosis. It will help ease my mind
