Having dull like pains two fingers under my belly button and nausea when i woke up this morning ? pregnancy? last intercross : month and 2weeks ago

Always possible: Take a home pregnancy test. You should be pos by now if you had intercourse 6 weeks ago and you missed your period. Otherwise it could be a hormone imbalance with a missed period or GI infection with an unknown cause for the missed period. Do the upt. If neg wait a couple more weeks and don't have sex if still no period then see a doctor.
