Had my period, but I still feel pregnant!!!

These are my symptoms: nausea, dizzy(bad), sleepy, stomach cramps, tingly and aching boobs, pulling feeling in my lower stomach, and a earache that is coming and going. I have taken 3 test and all were negative. One of them I took today. I only have pms symptoms the first 3 days of my period, I finished yesterday on day 7. Husband and I aren’t trying but if it happened, I would still be happy! We have a 7 month old boy together. 💙 what could this be????
