My belly button hurts

In addition to the frequent migraines, leg nerve pain, and freakish amounts of gaseous bloating exclusively associated (so far) with the third trimester of this pregnancy, I now have a sore belly button. It feels like it's stretched out and bruised. Alice's daily snuggles and lap-sitting moments are less enjoyable than they used to be :( New stretch marks also tell me I'm a little more round than I was with Alice. I'm trying to remain positive about these temporary physical changes, trying to see them as progress towards a very desirable end. I actually feel guilty complaining about physical trivialities when we've been blessed with not only another child, but a healthy one. *sigh* At the same time, I'm really looking forward to the day my guts (and his heels) move out of my rib cage.
