32yrs, 4wks preg, 2mm intramural fibroid. I want to terminate coz not ready. Risks?

No concern. The biggest concern I would have for you is carrying an unwanted pregnancy. The risks to you for carrying an undesired pregnancy are FAR greater than the risks of termination, regardless of fibroids. Even then, your fibroid is the size of a grain of rice, which would not concern me. Even if the fibroid is 2cm, it still would not be increase your risk related to pregnancy termination.
Safe. Early abortion is safe and risks are minimal. However, at 32 it is time to start planning when you will have children. Your risk of conceiving a child with down syndrome starts to rise at 35. In addition, your fertility starts to dwindle as your neat 40.
