Blood test

My insurance doesn't go through for another 3 weeks because its open enrollment. I can only be seen in the ER for emergencies. Should I have the blood test done in the ER? Just missed my period today. Lots of positive tests. Need to know how soon I should have the blood test done.

UPDATE:

Made an appt with a midwife 3 weeks out. Thanks for the help! Like I said this my first so I'm a little lost.
