I'm pregnant and slammed my thumb in the door 3/4/07 please help?!?

I'm about 3 months pregnant and slammed my thumb in the car door today (sounds dumb but I'm so upset at myself for doing something so silly).. My thumb instantly turned purple under the nail and swelled up 2x-3x its normal size. I put ice on it, didn't really do much. The throbbing pain is HORRIBLE.. I can't take it! I've been taking tylenol.. this happened at 12pm today and its 10pm and still hurting severly. I can't bend my thumb at all.. I'm not sure if it's because it's soo swollen! The pain is from the tip of my nail up until halfway down my thumb. It hurts even when I touch it or move. Actually it constantly hurts! I closed my finger in the door once before and I dont remember it hurting nearly half as bad! I'm wondering if I should go to ER or if it's just apart of a jammed bruised thumb! I don't want to sit in the ER waiting room for 4 hours for them to just look at it! It's not like I can even take anything else for the pain! Also I'm starting a new job 2marrow... Just great!!
