I am 37 weeks with my first 3cm dialated and 75 effaced doctor said anytime now if I want to have her is fine but that if I don't I should go on Bed rest is she just being dramatic?

It's better to deliver a baby closer to full term whenever possible. Sometimes nature wants the baby to come early, and that's fine. However, 37 weeks is in fact full term, so you can indeed deliver at any time and it's OK. Your baby is full term.

However, you should confirm that you are actually 37 weeks (full term). Could it be that bed rest was recommended because you're actually not 37 weeks? Please call your doctor and check.

In any case, follow your doctor's advice--whatever it is.
