Is this normal?

I think I might be prrfnant I feel so different. Not TTC but it may happen 😅 I've never charted this before but I decided to...mean anything? Huge headache 1dpo-6dpo. Cramps up until today and burping a lot. Dizzy, emotional crying spells, hungry but nothing is appetizing, pains in certain areas, sore nipples...etc
