Hi I am on nur isterate and have self Injected

Patient: Hi. I am on nur isterate and have self. Injected on the 10/01/15. The next morning I saw the paper bag very oily. I was supposed to take another dose on 07/04/15. My hubby n I had unprotected intercourse on 03/04/15. I missed my dose of nur isterate thinking I had to take it on 10/04/15. I didn’t get my period since. I have been getting weird symptoms since then like tender breasts, increased hunger, mood swings and frequent urination. Could I be pregnant? Or what could be wrong? I Am really worried now.

Doctor:
