Super confused... abnormally light period a week ago and symptoms this week.

Ok y'all here goes. A week and a half ago I thought I could be pg and then started spotting. Next morning red but not heavy on and off for a day. Then went back to just spotting. Very very light for me but still figured there was red so I'm not pg. then this last week I've been feeling nauseous on and off during the day with some hot flashes (weird because I'm usually cold) and headaches some and I can smell EVERYTHING! It's weird. So I took a test Tuesday night, a blue dye I'll post below. Thought I saw a faint line but maybe I'm nuts. Just figured I was seeing things but still felt nauseous and it seemed to be lasting longer. Not fun. So I retested with pink dye today. And now I really think my eyes are playing tricks on me. Anyways. Just looking for honest input. We weren't really ttc but if it happened I would be happy. But not looking for false hope. Honest input is best. Thanks so much. This community rocks!💜🤘
