Am I Pregnant!?

Ok so I’m 16 and my bf and I have sex a few times a week and he never cums in me. I’m on the BC pill that I take properly!! I had my period a little over 2 weeks ago and a week after my period I started to feel a little nauseous. This was off and on for 4 days. I’m also a really anxious person so it could have been caused by myself but idk. Then the nauseousness went away for a week and now I feel a little nauseous again. My period is due in 6 days and I’m rlly scared. Could I be pregnant even tho I take my BC on time? Help me😭😭 so scared idk y I’m nauseous:(
