Advice please

For the past 3 weeks I’ve been having very heavy boobs, sleeping more than ever &. Eating more. I took a clear blue test Monday it was negative, retested again yesterday it was a vvfl , took a cheapie this morning it was a bfn😢. Usually I’d cramp the whole 4 days until af shows. Only cramped for a day in a half . Af supposed to show on 4/6 or 4/7. What should I do? I’m not having my normal symptoms
