Hey Jenny, you're not alone. I've been having some bleeding issues as well. I had a regular U/S last month but haven't had an sonohysterography ultrasound so I can't help you out on that. I did have an endometrial biopsy done in the OB's office last week. Of course I was thinking the worst. There are lots of reasons for spotting tho, your OB is most likely looking for a polyp. That's what they found in my biopsy (which wasn't seen on regular U/S), all benign! Still too early to tell if it's been the cause of my spotting. Best of luck, update me!
