I've noticed a few changes since I hit my seven week mark, I get hungry more often (which I didn't think was even possible). If I don't eat the second I feel hungry then I get super nauseous, which is not a fun feeling!! I have become so tired lately too! I get about 10-12 hrs of sleep a night now that my tooth is feeling better! I get so tired with little activities , which Wes thinks is so funny, Like yesterday I vacuumed the whole house (which is only 4 total rooms) and after i was done I was telling him how tired I was ! He laughs and thinks it's so cute!
