Where Is My Period?

I missed my period last month (April), I recently been craving chocolate ice cream with brownie pieces, nutella, whipped cream and chocolate syrup. The other day a family member of mine was making fish, now normally the smell is a bit bothersome I just crinkle my nose at the smell this time I gagged and vomited a bit in my mouth and had to go upstairs and to my room to get away from the smell. I took a Dollar Store test and it came back negative, I made an appointment with my GP just to be safe. Would like your opinions and thoights on the matter, thank you.
