I think your confusion comes from the diagnosis that calls for methotrexate usage in a pregnant woman. For example, if a woman is pregnant, and has cancer, the usage of methotrexate to treat the cancer is licit and falls under double effect. The reason she is taking the methotrexate is directed at the cancer. The fact that an embryo will be affected is a side effect of the treatment acted on her. The intent is to treat the cancer. She can wait if she chooses, but she is not required by the Church to decline medical treatment for her cancer. But, If a woman is pregnant and doesn’t have any other diagnosis befitting methotrexate usage, and takes methotrexate, it’s because she wants to flush the embryo out, which is a direct abortion and is not licit according to Church rules.You are correct. I used the wrong terminology: I should have said that MTX is said to constitute a direct attack on the fetus, not a direct abortion (slightly different concepts). My memory is that treatments which constitute direct attacks cannot be covered by the principle of double effect.
Methotrexate is also used for rheumatoid arthritis, and often is prescribed to prevent permanent disability. So it could be licit for a pregnant woman to take it if she has rheumatoid arthritis in which delay of treatment might be detrimental to her health. It really depends on how bad it is, if she can wait, how the disease is progressing, etc.
