i passed out!? 😰

i'm 12w 3d and i fell today in my kitchen. i was standing, cutting a kiwi. my vision started going black, my extremities were tingling, and my ears started to ring. i walked to the table, sat down and tried to breathe.. but it continued. i was profusely sweating and moaning in confusion. i remember getting up to get water, but i woke up on the floor. my senses came back, but i am still shaky and chilly. i ate a banana, a kiwi, and some oatmeal. i've been hydrated, but i have a history of low blood pressure and diabetes runs in my family. should i be worried?! i left my dr a message, but haven't heard back. 😖
