Pregnant or Menopauae

Hi Can anyone help with these symptoms, I am 46 and didn't have a period for 96 days (in the last year my period have been on a 32 day cycle approx). My period last about 5-7 days with spotting either side of the period. At first, I thought I was pregnant as I had sore breast, nausea and cramping. Then on the third day I bleed for 4 days heavily and with the most horrific cramps and nausea. It's now 3 days since my period and the nausea is much stronger along with extreme sore breast and occasional cramping. I feel hungry, but when I do eat I feel nausea! Thank you
