Am i pregnant ?

I just had my nexplanon birth control removed! The doctor told me that i would be ovulating after the removal. Silly me had unprotected sex and now i am scared i could be pregnant!! Im having super painful lower back pain , ive been peeing every 2 hours and i feel so dizzy everytime i stand up but i havent vomited once 🤔 had a little spotting for two days but it disappeared ,its been a 2 weeks since my birth control removal .. could i be carrying my first child ?!
