Frustrated and confused HELP

Every month I get these symptoms towards the end of my cycle and the part that bothers me is that my symptoms are the same as what google says are early signs of pregnancy but then in the end I get my period. So frustrating that my period symptoms are the same as what people get for pregnancy symptoms. I never know if it is my period coming or the miracle of finally being pregnant.

I usually get tender breasts, sore nipples, cravings and food aversions. Large appetite. And then major mood swings/ anger and emotional/crying.

Is there any other symptoms that I can look for that will help me determine pregnancy from period?
