Stabbing on one side?

So I’m supposed to start my period tomorrow and this morning I woke up to these stabbing pains in my lower right side I mean it’s uncomfortable to stand or like stretch out my legs it’s like I can feel the right side of my uterus in ovary and there is this dull but sharp stabbing sensation that is coming and going? Any of you ladies experience this? They are making me nauseous also I tried to clear my throat and it caused like a shooting sensation in the same spot idk I just know it’s uncomfortable it doesn’t last long but my god I have never😭😫💃🏻💃🏻💃🏻 I don’t feel like it’s a pms symptom because I never get cramps this isolated before my period usually it’s more of a deep uncomfortable sensation all the way across like I ate something terrible and am seconds away from blowing up a toilet😂😂
