Feeling sick & in pain🤧🤒

Has anyone got sick prior to finding out your pregnant? Monday I was fine & everything was normal. I woke up Tuesday 03*05*19 feeling like I was hit by a Mack truck. I have wayyyyyy literally wayyyy tooo much saliva/mucus/Flem. I’m congested nose running back hurting & out of no where my breast feel kind of tender but bearable. Usually I can feel when I’m getting sick and can catch it. I didn’t even see this coming. Please share your thoughts & opinions❤️
