I went to my GYN for this, not GP.
I went in a panic last November because I had been spotting for 3 weeks, (just a wipe on the TP), that's when she did all the testing and determinded that the bleeding was coming from the fibroids. it finally stopped after 7 weeks. (UGH!). I haven't had any bleeding since.
She had me repeat the transvaginal ultrasound at 6 months, I went a couple weeks ago and this second showed they are stable. I am due to go back in December for my yearly, but don't have to see her sooner if I start bleeding again.
