am I pregnant?

Shayy
So I am about 4-5 days late on my period this month. Me and my boyfriend had unprotected sex quite a few times within the past 1-2 months. but he did not "finish" inside me. Also I take birth control. But I have noticed swelling in my feet, ankles, legs, and headaches and mild weight gain. I need some opinions on what you all think?
