How did you find out you was pregnant ?

I found out when I was a month. I couldn't taste or smell anything. Anything I smell would be the aroma in the smell. If I was cooking chicken I couldn't completely smell it all the way all I smelled was the frying smell. Also my belly was stretching and I couldn't sit straight hardly anymore. Also when I ate I was even hungrier. I didn't crave anything either. I also missed my period
