What do you think is going on with me? Honest opinions please.

Well you know how pregnancy and period symptoms mimic each other? Idk wtf is going on. I literally can’t tell. I’ve been having backaches, sore boobs, and a weak stomach (like low key slightly nauseous) I have been getting slight cramps but they come and go. This has been going on for a few days prior but no taste or smell adversions. Oh, and been feeling very fatigued. I not ready for a baby as yet so pregnancy is out the question. My period is due today. What do you guys think? pregnancy or period? Everytime I think it’s about to full on start it doesn’t come down. Idk. I’m stressed right now.
