Text says Draupadi was happy to marry five. I think she had some memories of her past birth since she was Ayonijaa.
Later in Vana Parva, she proudly said, varne pancha Janam patitve. Means I did the varan of five men as my husbands. She was always proud to call herself as a wife of Pandavas and never in the epic she regretted for her marriage.
Hope this clears all doubts.
