Whhhat do you thiinnnk 😭😭😭

My period last month came on time & it was regular I don't have any symptoms of pregnancy -although I have a sever depression- he didn't come into my vigaina or even near it & we didn't had intercourse + I'm a virgin..Β 
I lost my appetite & 1.5kg because of stress .. but i'm still scared .. could i still be pregnant ?
