10 days late!!

Hello just had a quick question , im 10 days late but got 2 negitive home tests already. I have naushea, light headed, almost fainted in walmart i drink pleanty of water i get hot sweats at night and durring the day i have been noticing myself over eat and use the bathroom more frequently i also have servere baxk pack in my lower back and hard for me to stay asleep at night but easy to sleep durring the day. Should i wait a luttle longer and do another home test or should i go see a doctor and do a blood test? Last time i tested was 3 days ago.
