PMS OR PREG⁉️

Natalie
Hi everyone!! I'm fairly new to this app and so far I 😍 it! I need some heals because my daughter 6 so it's been a while since feeling anything lol 
I have had my period like regular. My last one was the beginning of this month and was 3 days long. But this week I've started having super sore breast and nipples hurt so bad, bad enough I don't to wear a bra... I'm getting hungry at weird times and I have been super tired. 
I've taken pregnancy tests and they are all ❌. Could it just be PMS?
