Pregnant or not!? PLEASE HELP

Dynasty
I'm a lot more tired, I can never get full and I'm eating 3X as much as I used to, I have a lot more discharge, I'm having serious heart burn, and my sex drive has increased dramatically but I've had my period for the past 2 months. Me and my BF use the pull out, and birth control. I'm just worried because my mom had her period for 2 months when pregnant with me, she took 7 pt and only one came out positive. I took a test last week but she wants me to take another one next month because my first one came out negative.
