went to the doctor guess my check up isn't till June 28, 2016 and my blood work isn't back yet so they said to save me the trip they will call me back and let me know the results which I don't know how long it will be should I let my Dr know that I was poked with a needle at work? since my re-check with him will be on June 17 or should I wait it because if the lab calls me and tells me the test are negative then I'm in the clear I don't really know what to do what would you do? let you obgyn know about this stuff?? wait it out? say nothing?
