xiaozhu, if its inside then u can't remove it until birth. Maybe u shd avoid food which may cause the fibroid to grow bigger. I was told to avoid nuts and soy products.
My gynea's concern than was tt my cyst may harm bb's head growth when there is not enough space. There is a thread on fibroid where mummies share their experiences, u can find out more from there.
In any case, dun worry too much and take care of ur health....ur gynea shd be watching ur case closely
