She asks: “Did I, indeed, have a twin at the beginning of my pregnancy, and has this in any way contributed to my placenta previa?” What can we tell her?

That, in fact, is the case. Both things are true, that there was a twin and it was a factor in the mislocation of the placenta of the remaining twin. That is, in part, the karmic underpinning for this happening as it is a kind of karmic recapitulation of prior history in child-rearing. You had a lost pregnancy in another lifetime, and that karmic backstory came back around again through the Law of Karma in your current incarnation. We see this as working out without any further complications. You will be in good hands and we will be watching over you to ensure things go smoothly.
