The point is that Mississippi and Denmark agree on the core moral question of when a fetus is developed enough that the fetal life outweighs individual autonomy in the ordinary case. Both draw the line at the end of the first trimester, when the fetus has a face, hands, fingers, and begins sucking its thumb. This is a fundamental difference from Roe, which draws the line at the end of the second trimester, at viability.

Moreover, both agree that there are extenuating circumstances that can change the balance in specific cases. And they agree on the particular extenuating circumstances that are most likely to arise: risk of severe deterioration to woman's physical health, and fetal abnormalities.

All you're pointing out is that Denmark recognizes additional extenuating circumstances for special cases. Specifically, the health exception covers the risk of "severe deterioration of woman's physical or mental health." But note that the "risk to a woman's life or to her physical or mental health should be based solely or principally on circumstances of a medical character." The other grounds for second trimester abortions require unanimous approval from a special committee: https://cyber.harvard.edu/population/abortion/Denmark.abo.ht.... They are not an open-ended exception to allow second trimester abortions in ordinary cases.
