As a very long term player I don't see EA putting half of what you are requesting in the game, at best it would raise the game rating and at worst make the game unsuitable for many, including children who play and potentially trigger (and alienate) those who've sadly had losses or struggling to get pregnant in the first place. It's quite a grim topic and might be too much "realism" for them. As I said before to each their own, some people's pain are other's pleasure. Chances are though it would probably get the Parents groups up in arms, calling for boycotts, sigh…again.
Food cravings might be a more... shall we say realistic and non-controversial request to consider asking EA for. It has a humorous side which they can draw from. Hey you never know, we could get Cucumbers, Dill and Pickling added to the game which seems like a win-win as Pickles are a common craving during pregnancy.
As a suggestion there is a Pregnant Mother Simulator game that puts you through all that gross stuff. If you're interested all you need is to put in those key words. It's still a little cutesy though graphics-wise. I've never played the game so I don't know how interesting it might be so this isn't an endorsement for the game, to be transparent. I've already done all that personally and it was the worst time of my life so it holds no interest for me as a form of entertainment, hence my lack of knowledge about the game. I hope that helps.
