Here's a compiled list of all potential side effects and complications that may arise during pregnancies: https://www.reddit.com/r/childfree/comments/8b0tho/i_made_a_list_of_all_the_bodily_risks_of/

Of particular note are:

Change of foot size\ \ Tooth loss / damage\ \ Osteoporosis\ \ Abdominal Muscle separation\ \ Genital tearing and prolapse\ \ Spontaneous coronary artery dissection\ \ *Organ failure

And this is just scratching the surface. In the best case, pregnancy results in undesirable and potentially permanent alterations to one's body. In the worst case, pregnancy can literally spell death.

I think if all of this was more widely known, men would think twice before talking about "actions having consequences" and pressuring women to "carry their children".
