I had unprotected sex on week 3 of my first

Patient: I had unprotected sex on week 3 of my first month ever of taking birth control. Also the 7th day the condom broke. And I have been experiencing diarrhea so I’m not even sure if the birth control method has been working efficiently. I have been dizzy nausea loss of appetite breast tenderness low back pain cramping.I got spotting dark brown and when I wipe it is very light red almost clear. Could I be pregnant.
