Could The Delayed Periods With PMS Be Due To Menopause At The Age Of 39?

i am a 39 year old female. since two weeks i have been drinking hot water with lemon and honey first thing in the morning. i always get my periods after 25 days but this time its been 35 days i havent got my period, although i am getting cramps and very painful breasts this is common for me when i get periods. i also did a home pregnancy test which showed negative results, please advice me could i be heading for menopause?
