Hello, I have not had my period since Nov 16th and since Nov 30th, I ve been having hot flashes. I remember feeling sick after Thanksgiving day but didn t think much about it, then the hot flashes started. I took two pregnancy test in the past 3 days and they both showed negative. Please Help! Could I still be pregnant, is this pre-menopause? I just turned 34 on Dec 29, I weight about 140 lbs and is 5 3 . Thank you in advance for your help.
