I wish I knew what's actually going on

I am 5 days late for my period but I've been having severe cramps like it's my first day on it for about 5 minutes in the morning but then it stops and doesn't happen all day and then I have slight little cramps throughout the day and no bleeding at all and I've been feeling sick for the last few days I even couldn't keep my lunch down today and I've been feeling overly heated the last two days. None of this makes any sense to me 😞 I'm scared I may be pregnant which I would love for so much but I know I don't need a baby right now either.
