Need some help ladies!

I had AF the 7th of November, wasn't a normal one. It was lighter. Bled off and on until the night if the 9th. My bf and I have been having sex every night to every other night since. Glow says my fertile days start tomorrow. But the past week or so I have been having back/side pains, dizziness, nausea, headaches, very sleepy and a feeling of fullness in my stomach. Could I be pregnant? I don't want to test yet. But I wonder all day long! Thoughts please??
