feeling sick

So according to the app I'm 5 days late. I woke up this morning to go to work at 5:15am & once I got up from bed I immiedetly felt nausea idk I just felt sick. It's been hours & I still feel nauseas, my boobs have been sore for like a week on & off, my head hurts, my body aches like if I was getting a cold but I was perfectly fine lastnight. Usually when I'm about to get my period my lower back aches really bad & that's not happened
