Doubt it. Zelena said she was born before Cora wormed her way into royalty, and since she didn't magically got pregnant while engaged to Henry, it couldn't have been during her love affair with Rumple, which was during her engagement.

I'm guessing Cora was raped by a villager (maybe too dark for this show, since the last rape we saw was Graham's back in Season 1) or she had a love before Rumple who died, and she couldn't bear to see the reminder of him (Zelena) every day.

But who knows? We'll find out in the next three months.
