Ive had 8 ultrasounds done already. all 10 minutes or less. all transvaginal. im only 9w1d. its my first pregnancy and i been having some spotting. ive been having these scans to locate potential problem but can too many scans harm the twins?

Wouldn't think so: These have been done for decades without effecting the outcome of pregnancy. They do give information you could only guess about before they came along. There are basically sound waves that are generated & bounce back to the probe. It does not involve radiation or other such things we do stress over. It can be confusing since many are done in the radiology department.
