Symptoms

Hey guys so I’m currently 6 dpo and I’ve never been pregnant before but for the past few days I have felt sooo nasueous like I could throw up at every single meal I eat!!!! My head hurts so bad I can barely keep it up! I have been taking so many naps! I’ve never done all of this before should I already be getting these symptoms is this a sign or what?😳 and Im extremely moody!
