I feel bad

We're having our second baby. Everything about this pregnancy has been 180 degrees of different. I was severely sick starting at 5.5 weeks and by 9 weeks had to be put on the strongest dose of medication. I lost twelve pounds. I'm finally putting some of the weight back on at 16 weeks. I'm exhausted every second of the day. The baby's heart rate was faster. The baking soda and ring test said girl. Chinese gender chart said girl. And the ultrasound specialist at 12 weeks said he was pretty sure it was a girl. 

Well, I went to an elective place last week at 16 weeks for gender (not a doctor) and we were told boy. Another boy. I'm a bit heartbroken. I of course love the baby and I know it's fine. But I wanted my princess. I don't think with all my health issues I will be able to have another baby.  I'm just trying to work through it and be happy. The baby is healthy and that's what matters. I just want to know I'm normal, not a bad mom and not alone.
