I am pregnant with my 2nd child. My son is 3 (today is his b-day). We are hoping for a girl, but after two miscarriages, we are hoping for a healthy baby. I am currently 17 weeks pregnant. I am anxious for 20 weeks to get here so that we can see the sex of the baby. So far this pregnancy has been a lot different than the first. I have head aches and heart burn all of the time. I have been sick more and I am more tired.
