Short version, stop taking these a few months ahead of trying to conceive, same general precaution as with most medications when it's an option, since long-term safety data just doesn't exist yet. We're really just at the beginning of figuring out whether it's safe, and it'll probably take a long while to nail down properly since no ethics board would ever greenlight a formal pregnancy trial. Realistically the answers will come from years of accidental exposures adding up across the population. Nothing alarming has surfaced so far, and current findings suggest early pregnancy exposure likely isn't a major concern, but that's absolutely something worth getting expert guidance on if pregnancy happens while still taking it, and no provider is going to advise staying on it through pregnancy until the data's far more solid. Given how many unplanned pregnancies have happened on this medication already, early pregnancy safety data will probably get sorted out faster than usual.
