Talk to your OB: You should discuss this with your OB and have a plan of action before you get pregnant. There are several options available to you.

Hmm.: Your uterus won't 'burst' or rupture if you get pregnant. That is a risk is you have had certain types of surgery on your uterus (c-section, or myomectomy) and become pregnant. But if you have never had surgery on your uterus it would be extremely rare for it to 'rupture'. If your uterus is really that enlarged from the fibroid, it will make the pregnancy high risk and fibroid may need to be remov.
