Your appetite's back: Don't be alarmed! you're in your second trimester of pregnancy now! in your first trimester, noticed a decrease in your appetite, with morning nausea, & occasional vomitting. Now, your appetite is back, and you're experiencing the usual cravings associated with pregnancy. Of course, these cravings can occur any time after the pregnacy hormones show up.
