Could I be pregnant? Or crazy?!

Okay... So I've just lost about 30 pounds lately. Been working out and trying to be healthy. I stopped my birth control for medical reasons over 10 months ago, my husband got laid off and got a job about 2 hours away. So he has been staying there and I drive up to visit in the weekends. We had sex twice while I was ovulating a little over 2 months ago. I still haven't had a period. I have had very light spotting here and there. But I'm exhausted. All the Time. Pretty rideclous. And my entire body is sore. And when I take my bra off feels like my nipples are on fire. (Sorry). I want to take a test. But I'm worried about both outcomes. What do y'all think?!
