Could I be pregnant ?? Please read

I believe I got my positive opk Wednesday 14th we BD twice that night and once the night after. I’m 10 days away from period (I’m irregular) could I be pregnant?

I feel like I would when my period comes .. aching back hips , and I have shooting pains in my stomach. Also no appetite.

I know it’s too early to test but I did anyway and I’m sure my eyes are playing tricks on me..
