Can you call the Dr? If he knows he's sent you off in a state of confusion, he should take the time to explain things to you.
When pregnant with DD2 I had an u/s come back saying she had cysts on her brain and I rang later that day (the Dr didn't even talk to me about it) it was a friday, and didn't give up until a Dr called back on the saturday! He calmed me down straight away.
Worth doing for your piece of mind xoxo
