pregnant?

        So, I've been having a lot of pregnancy symptoms these last few months. My boyfriend and I had unprotected sex in July, he isn't sure if he pulled out all the way before he actually came... Neither of us know for sure if I am pregnant or not... I have been pregnant before, but I had a miscarriage in November of 2015. I'm only 16, almost 17, and my boyfriend is 22 he asked me to marry him not long ago, I said yes. I feel like it's just because I might be pregnant, but he says it's because he really wants to spend the rest of his life with me.
