18 weeks!

I am growing at a very rapid rate it seems lately. Here I am at 18 weeks. I don't really think I look this pregnant until I see a picture because with it being cold and all I am usually in a sweatshirt and bundled up and don't notice the belly so much. I have been feeling really good, except I think my thyroid levels are low, my doctor wants me to get it checked in a month again. I am on a supplement already, but I have been tired, my hair is falling out like crazy, my skin is super dry, and not to mention at my last appointment I gained a ridiculous amount of weight in a short amount of time. So I am hoping that my dose will get increased soon so I don't become bald, gain 100 pounds in my pregnancy, shed skin like a snake everyday and get nothing done because I am too tired. Once the thyroid stuff is figured out I think I will be feeling really great, but I have still been feeling good so I can't really complain. My next ultrasound is coming up soon and I can't wait for that! I especially can't wait for Eric to see him! I will have so many pictures of this little guy before he is even born!
I also want to say that I still think constantly of those who are still going through infertility!!! I met some great people online who have been through a lot and still praying for a pregnancy. I don't want to sound like I have forgotten just because I am pregnant, I havn't! I still think and pray for them all the time! I hope I don't sound like I am gloating, I hope it gives hope that pregnancy is achievable, even after 1 1/2 years of taking all the medications available!
