I need some serious help...

Okay so i just started birth control and i’m still a virgin so there is NO WAY that i am pregnant but my head is telling me that i am. and i just got the flu or something and i’ve been throwing up.

i have only taken birth control for 10 days and me and my boyfriend haven’t done anything to where i could be pregnant. so it’s all in my head, right?

i just can’t stop being paranoid about it. and i’m constantly thinking about it and my boyfriend has actually started to worry about how much i’m thinking about it. i know i’m not. i know i can’t be. it’s all in my head but yet i can’t seem to stop.

does anyone have any ideas how to stop me from feeling this way? please. anything would help.
