Objective negative? Come on, be serious.
A parasite sucks up nutrients and energy from its host, forcing the host to overcompensate. A parasite that causes the host to vomit will also induce weight loss and allow the host to eat more.
It's anecdotal, but I have heard many women list the ability to eat more as one of the few positives in the pregnancy experience. Pregnancy is clearly a mostly very unpleasant experience, climaxing with childbirth. Women aren't having kids for the pleasure of pregnancy, so coming at pregnancy with any such concerns (which is what the horror music take on it does) misses the point of having children.
