Maybe low sugar?

So idk what happened to me this morning. I'm about 99% sure I'm not pregnant bc AF just left me. However, this morning I woke up with the worst left sided abdominal pain and left sided back pain so I went to the bathroom to try to take a bath and I went to pee and I started getting so incredibly dizzy. (So typically thought maybe my sugar is low,personally never suffered with sugar problems) I woke my husband and he got me some orange juice. I went back into the bathroom and all of a sudden I got nauseated and three up the orange juice I drank. Felt a little better enough to get off the bathroom floor went back to bed and I'm perfectly fine now. Does it sound like a low sugar issue
