ADVICE PLEASE!😷😢

I am currently 36w2d. I woke up this morning feeling really tired, nauseas. Then started feeling lightheaded, still nauseas, shaky, extremely fatigued. I had some what I think is braxton hicks on and off this morning nothing regular. I have eaten breakfast and drank some juice. I just don't feel like myself. Anyone else have this happen around this time? Anyone know what could be going on? Any advice or help is definitely appreciated! Thank you in advanced.😊
