So i got my period around the final days of august and it ended on the first of september. then I had unprotected sex on September 2 and took next choice that same day. Then I got my period a week later. I calculated tha my next period would be around the beginning of October but it is now the 9th and it still hasn't come. I have weird feelings in my stomach but I'm not sure if its pms or if I'm pregnant. I've been stressing out lately. Will I be okay?
