Feel pregnant but have 4 days til period:(

I have had the past two days horribly sore boobs and at the same time both days get this awful headache with dizziness and nausea yesterday I for sure thought I was going to throw up (same thing today 🤢) I had horrible headaches and dizziness when I was pregnant with my 1 year old.. is it to early for signs or has anyone experienced this and found out they are indeed pregnant?! I just have this feeling! I also went running today and felt a heaviness in my lower abdomen, my boobs felt heavier and i had a sharp pain in my lady part area (TMI sorry 😳)
