Ever noticed how most drug labels say, "Not recommended for pregnant women"? It's not because clinical trials found those drugs to be harmful-it's because no trials were done at all. And guess what? Pregnant women still get sick and still need treatment. But no trials mean limited options. Why no trials? The answer's pretty obvious: clinical trials only happen when the potential benefits significantly outweigh the risks. Pregnancy cranks up the risk factor, so unless the benefit is undeniably worth it, no one's going to run that study. It's a tough trade-off, but it's one rooted in protecting both the mother and the baby.
