could I be pregnant?

So my fiancé and I started having sex about 2 weeks ago. I'm on birth control but he doesn't wear a condom. We go with the pull out method, and have only failed at that twice. Recently I've been experiencing headaches, dizziness, cravings, cramps, and occasionally nausea, I swear I can smell things more too. It's about 8 days until my projected period start date. Could I be pregnant or maybe just PMS or anxiety about it all? I usually don't have PMS symptoms like this and definitely not this early on. Thanks for the input!
