I am a 42 year old female. My periods are always on time or early, but I missed this last one a few weeks ago, but for over 3 weeks I have had the cramps like I do when I have my period before and after it was due, severe night chills where I wake up drenched in sweat, and as of last night I have severe abdominal pain with bloating . I have high blood pressure (medication controlled), GERD w/hiatel hernia (medication controlled), had my gallbladder out in 2010, am not using birth control (just condoms), same partner for 22 years. Not trying to get pregnant.
