Need Help

Kate
So a few days ago I got very sick, constantly throwing up and had flu symptoms so I figured it was just a virus. I have also had symptoms of what seems to be a yeast infection. lucky me.... I don't know if this is a bad sequence of events but I know both are caused by pregnancy. my (now ex) boyfriend and I had sex 2 weeks ago. I had my period a week ago at my normal time and I have continued to take birth control. I'm not sure if I'm just being paranoid or if I should be actually worried
