Hello, I Am A 37 Year Old Female. I Had

hello, I am a 37 year old female. I had a tubal ligation done over 3 years ago. I am sexual active and have not used any contriceptive since the surgery. the first day of my last period was 2/14/2016, I have taken 2 pregnancy tests and both were negative. I thought I was getting my period around 3/18/2016, as I became bloated, had cramps, and hormones were shifting...I have not started as of yet. I have sore and tender breasts, I have periodically gotten nauseous and thrown up at different times of the day and night....I have read up on menopausal symptoms, and do not have any as of yet. any ideas or advice?
