Shocked

My boyfriend and I haven't been trying to get pregnant, but we haven't been trying to prevent it either. I took a test today because I just had a feeling (even though last week I bled for four days) I'm in shock! I'm happy, scared, excited... All of the above. We had an eptoic pregnancy in March so I'm so so so scared it will be another one, but I'm just praying everything will be okay. I'm not sure what to do next... Any suggestions?
