Well if you were having unproc/ sex then most then likely you are, it's well over a month. congrats if thats what you want but you honestly need blood work done. Go to the e/r they'll see you quick and they will perform all the necessary precautions to give you a pos or neg result. Goodluck keep us informed.
I would go to a doctor and have them do a blood test. A friend of mine didn't get a positive hpt pregnancy test until she was 3 months pregnant. If you are usually regular and haven't had a period in that long, then definitely go get a blood test done!
