A.S.
I had one the size of a grapefruit that was in all three layers. It did grow a bit because of the hormones but my doc didn't put me on any restrictions or refer me to a high risk.
I did have bleeding off and on during my pregnancy during the bleeding. It was so heavy during the 5th week we thought we miscarried.
I did end up having a c-section because of where the fibroid was (low and to the right). We weren't sure if the baby could make it past so we opted to schedule the birth instead of risking an emergency operation during labor.
You may want to seek a second opinion regarding the need for a high risk doctor and the restrictions.
Oh and if the baby is really active with the punching and kicking you may feel like your stomach has been run over by a bus. Hopefully your little tot won't use it like a soccer ball like mine did for a while.
