4 weeks & 2 days

Today I'm 4 weeks & 2 days. I didn't think I would experience the things I am so early on! I've had heavy cramps since Sunday which is when I found out I was pregnant. Today they're subsiding. I've been tired but not overly exhausted. When I get hungry, I get really hungry! Lol The past 3 days I haven't been able to get a full nights sleep. I'll wake up anywhere from 2-4am. Sometimes I can go back to sleep and other times I can't! Last night I was up from 2:30-4:30am and was super hungry! Anyone else going through this?
