Went from nauseous to STARVING

Hi all! I’m getting worried over here. I’m about 5 weeks today. I had been getting cramping and some food aversions. They stopped yesterday afternoon. All of a sudden I was starving like insatiable hunger. My boobs are still huge and sensitive. I’m terrified of having a chemical. My clear blue and first response tests are strong but I’ve been taking the premom tests as back up and they have looked the same the last three days. By this time with my July 2019 baby I already had a matching control and test line on the premoms and mine aren’t even close now. I also had really terrible morning sickness the entire pregnancy with my last so I’m worried that the food aversions/ nausea seems to have gone away. Anyone have any experience with any of this or any advice? I don’t have my first appointment for another 2 weeks 😔
