Weird pregnancy symptoms!! 5 weeks! Due around January 2017. Any pregnancy buddies out there??

So I found out that God blessed me with our baby blessing this month. I'm around 5 weeks, almost 6. Found out the 18th this month (may) and I've been having hcg quants taken every 72 hours. Last time I knew it was only 188 (2 days ago). I've been extremely hungry at night! I can go all day just snacking a little here and there, but as soon as I lay down to go to sleep all I can think about is stuffing my face with hamburgers and hotdogs!!! I also have this weird tingly sensation that runs through my whole body when I walk around and pretty much move in general. Wondering if that's normal.....I also have cramps that come and go. Only last for about 30 seconds or less. Should be due around January 2017. Any pregnancy buddies out there??
