The conflicted expression was intentional, yes. In addition to the long term worries you mentioned, she also has the immediate concern of being the center of attention while in such a state.
I dunno if the artist consciously and deliberately rendered her expression so that her smile looks equal parts natural and forced, but that's how it looks to me! She feels that maternal giddiness that her obviously and unconcealable state of pregnancy brings upon her -- an effervescent anticipation that's coupled with a nagging worry for all of the unknowns that come with being a first-time mother that she doesn't have any control over
1.I'm disappointed we didn't get to see more fun with them in bed but I hope they comeback down the line. Probably making space for more lighter chains.
2. She's pregnant and I did the math, she's stuck like this for the next 10 months and if the baby is in its 8th or 9th month it means she will be normal again after however there's a good chance she may have had more sex with the guy.
3.the rose pedal is a nice visual gag, I love the idea that everyone except her has a face, the baby will probably be like that too funny enough, hope we see more of these two down the road but for now we're on to the next adventure.
