What do you think I'm having? I find out in 6 days!

So, I've had really bad morning sickness. I've thrown up so much that I've lost 9 lbs in the first trimester. I was 119 before getting pregnant, then 122, then down to 113. Now I'm 114 lbs. I'm 15 weeks pregnant today. I still have morning sickness. I threw up two days ago, but that was the last time. I still get sick with eating some foods and I crave pickles, skittles, and bbq chips. Also, my baby's heart rate was at 165 bpm at 12 weeks pregnant.
