Feels pregnant but negative?

On 15th july, i was admitted cause keep vomiting non stop till i nearly fainted, dr test pregnancy, it is negative. He then do ultrasound, then said that there is a small tint thing which might be a kidney stone which then ask me to follow up next month. End of month, 28th july, i missed my menses, so i do pregnancy test again, anddddddd im pregnant😂😂 so the kidney stone is not a stone, its the baby😂😂😂 sometimes, it is too early to check, wait fot ur menses and try again🥰
