Help!! Stupid question! 😂🤷‍♀️

So this is probably a stupid question but me and my boyfriend had unprotected sex a week ago. I had just got off my period. and I have been off birth control for about a month now. I know it’s really early. For the past couple days I have felt super bloated, been fighting headaches, sharp stomach pains and today I started spotting. Is it possible I’m pregnant? I haven’t taken a test yet because I feel like it is too soon. I’ve also felt like throwing up the past couple days but that’s probably due to a lot of stress that’s been going on. The big question is would I be able to tell this early?
