I'm 18 weeks pregnant and just had my 18 week ultrasound. I was told at the ultrasound that I had four fibroids, one tiny one, 2 smallish ones and one that is 7.5 cm. I was also told that the 7.5 cm may block the birth canal but it is too soon to tell. I found out I was sent to a high risk specialist because of my fibroids and will need follow up ultrasounds. I personally am concerned about the effects of several ultrasounds and wanted to know other people's experiences. Have other people with fibroids been sent to a high risk doctor for them? Do all people with fibroids have additional ultrasounds or is the place I am going being extra cautious? Also in case I am told I need a c-section in the end is it worth getting a second opinion? Has anyone been told by one person that they can't delivery naturally due to fibroids at one place but been able to do it elsewhere?
