Period or pregnancy symptoms?

Hey everyone! I already have a 2 year old daughter but I have a strong feeling that I might be pregnant again. I don’t start for another 5 days and I took a test this morning that said negative but I’m waiting till I either start or miss my period to test again. I’ve been pregnant twice (just had a miscarriage the second time) I know what my body feels like in early pregnancy. My boobs are starting to hurt more frequently, I started throwing up yesterday, I have light cramping on one side of my pelvis, I’ve been getting dizzy a lot more and I can sleep a good 10hrs a night and be exhausted when I wake up…. I could just be paranoid also lol but I’ve never had these happen all at once during my period only early pregnancy..
