Your sonogram report shows that you have a viable 6-7 weeks pregnancy
. There is no remark about the fibroids that were noted in the earlier sonogram. You need to correlate this with your menstrual calender if you have regular cycles and also through clinical evaluation. A trans-vaginal sonogram is ideal in this situation to know the status of the pelvic organs, especially the endometrial cavity, better. Since you have used an antibiotic, this should be reported to the specialist as a watch must be made in future for anomalies. Hope this helps.
