I need an Advice 😣

I’m 4 days late and I’m pretty regular. I was feeling weird the last couple days but yesterday night and this morning the dizziness and nausea have increased. Also, I have been feeling little cramps. I took a test two days ago and was negative, I did it in the afternoon. I'm not sure how long should I wait to take another test and if I have to do it in the morning. This is driving me crazy 😬
