Could this the mobth for us?

OK I was due to have my period today but yesterday I was spotting most of the day. Today I just had some mild cramping with a brown discharge and that was it. I been have sore boobs, tired all the time, eating more the I normally do, have dry mouth, have a lot of gas, heart burn, and feel extra bloated. Any advice, could this be the month for us? Thanks in advance
