Need opinions!

Courtney • Recently had nexplanon removed! Just went through a chemical pregnancy! 😔 Praying for Baby #1!
So I'd like some opinions. I am 7 dpo. I had a brownish discharge about 5 days ago also that night my legs felt like jello and ached really really bad! It was gone the next day! Then about 3 days ago I started this thing where I can't really eat because when I see or smell food I get extremely nauseated! My back hurts, I have a terrible headache (constantly), my boobs feel really soft and squishy (they're typically extremely firm) an they ache. And I'm extremely emotional; beyond belief. Do you think it's too soon to take a pregnancy test??? What is everyone's opinion on my symptoms?
