Getting Puffy!

I have not had any swelling until this week. Suddenly, in the last two days I have ankles no more. And, I'm not going to be able to wear my normal socks anymore due to the elastic in them cutting into my legs. My Mom & Granny & Lance seem to all be really concerned about the amount of swelling I have done this week. But, I really don't think there is anything I can do about it, or the doctor for that matter. I go to the doctore again on the 31st for a sonogram, so I am going to try to hold out until then and see how I do. However, I have gained 5 pounds THIS week! It has to be fluid gain. I weigh 165 today, that's 30 pounds weight gain since pre-pregnancy days. I am getting tireder everyday it seems, and my ability to sleep at night has pretty well disappeared, I get up multiple times a night, and I just can't get comfortable anymore to sleep good. And, baby boy Mabe is kicking me and moving all the time. He is very active and I feel like I have a CRITTER in my belly most of the time because it is just so odd feeling. The most enjoyable part of pregnancy has to be feeling my little boy stretch and move. Any body have any advice on how much swelling is NORMAL during pregnancy and when should I be concerned? I am 25 weeks now! That is crazy! But, at the same time I feel like I have been pregnant a whole year. In just 3 short (I hope) months, we should have Mabe Babe here! I can't wait to meet him!!!
