Bun ? Or none ?

Period 3 days late , lower back pain , headaches and cramping .

Past 2 I’ve been felling sick . Last night I woke up at 2am feeling super nauseous and upset stomach. Took tums to help with nausea. I would never get nauseous like last night , has this ever happened to anyone. Any comments are welcome. Ty .

Anyone else in same boat or has been ?
