You should be getting your cervix checked soon, anyways. They will see it then and you will feel better! :)
Ill try ... im worried its gonna get bigger
also soak a pad with some witch hazel, cool it down in freezer and try that, externally only :)
they are quite common, I would treat it like a hemoroid and try a cold pack on it and its prob not possible but try and stay off you feet as the pressure from baby will be making it worse, not very helpful sorry
