Death as pregnancy? Maybe reversed more than upright...but I think you would need a few other cards in conjunction with Death (or any other single card, for that matter) to indicate a possible pregnancy. So, to me, it would be a stretch to see Death suggesting pregnancy in the first case. (I'd be looking more for the Empress, Ace/Page of Cups, Ace of Pentacles, maybe...as a possibility to suggest a possible pregnancy, though I still think any card combinations would only suggest the possibility without definite outcome.)
Also, I think the pairing of Death and Three of Swords could suggest miscarriage in a situation where one already is pregnant and known to be so, but I think some other pairings might show up to better predict the scenario you described: a future pregnancy that ends in miscarriage. You may be putting the cart way before the horse here. IMO
I never bend, fold, or mutilate. Unless I'm in a hurry.
