I agree with alaysha and GA, but for a different reason. both of my pregnancies were so similar during the first and second trimesters that I thought I was definitely having another girl this time, but I'm having a boy. It's a little different now that I'm in the 3rd trimester, but the only big difference up until now was where I was carrying the baby (high vs. low) other than that it was pretty much identical symptoms. so it's nearly impossible to tell by symptoms.
I agree with LosingMyMindInGA. I have a little girl already and this pregnancy has been SO different so I was sure it had to be a boy. Nope... its another girl.
your symptoms are not a good indicator of the babies gender. I have had 3 boys and 2 girls and am pregnant with another girl and my symptoms have varied widely with each pregnancy.
I had all the same symptoms that you are describing with this pregnancy, and I am having another little boy =0), I just don't know if these symptoms are guaranteed that you will have a boy. If your really curious to find out what your having you can try taking the intelligender test found at Target for about $30, I took it at 10 weeks and it said boy, and then at my ultrasound at 19 weeks it was confirmed that we are having a boy. Hope this helps and Congrats!
