As stated in Timatic, the database used by airlines:
Visa required, except for passengers with a family member residence card issued by Switzerland or another EEA Member State. The card must be issued to family members of a national of Switzerland or an EEA Member State. They are visa exempt for a maximum stay of 90 days and must travel with or travel to join the national of Switzerland or EEA Member State.
So no, you do not need a visa for Romania. However, you need to bring proof (phone number, other documentation) that your Family is in Romania and that you will join them.
