3 days until my period

Not having my regular period symptoms. My boobs are very tender. I have also had diarrhea the past two days. I literally don’t have an upset stomach or any other sick symptoms and I never get diarrhea. Is there any chance this is a early pregnancy symptom? I know hormone changes cause diarrhea. And before my period I usually don’t poop a lot. So this is a little out of the ordinary for me. Sorry if that’s all gross but I’m just hoping for a baby.
