I fell and I don't know what to do 😅

Summer
Lastnight, I went to put air in my tires and somehow, I tripped and fell in the parking lot... I landed on my knees and my hands. My knees are now bruised, my right ankle feels like I either twisted it really bad or sprained it or something bc it has a horrible pain on the outter side of it that shoots up my leg to my knee. i've never had broken bones, fractured anything nor sprained anything before so it's hard to explain. I'm having weird, unusual sharp pains in my waist area and I've been feeling very nauseuous since lastnight. I'm 14, almost 15 weeks pregnant and it's starting to scare me more today bc I have all of these pains, whereas I did not lastnight. I probably should have went to ER lastnight, but I didn't.. Should I go today or will I be fine? 😅😕😣Â
