I’m rather skeptical of this, because it seems that morning sickness eliminates nutrients as much or more than toxins.
Harm and benefit are not equally balanced. If you snarf down some hemlock, the minimal calories you gain from digesting it do not offset the poison you’ve ingested. One bad meal can kill you (the Buddha died of some bad pork, legendarily), but skipping one meal certainly won’t kill you. You would have to skip a lot of meals to equal one bad poisoning episode.
Is there some indication that morning sickness is related to ingesting harmful toxins, now or in the evolutionary past? It doesn’t seem from my experience (close second hand only) that morning sickness is more than increased sensitivity to certain foods, and rather a general nausea that makes many nutrious foods difficult to keep down.

Such as one or two a day for 2-3 months?

Morning sickness can get that bad, but it’s rare.
