Confused

My boobs started hurting a little over a week ago and they still are hurting (which is a normal period symptom for me) my period is not due until the end of the month. Now I have a slight headache and feel nauseous. I haven’t had sex before. I’m still always paranoid that somehow get pregnant even though I know it’s pretty much impossible. I just have bad anxiety😂. Can these be normal period symptoms as well? Thanks :)
