When it comes to medication safety during pregnancy, it is crucial to approach the topic with caution and thorough understanding. The use of any medication during pregnancy should always be discussed with healthcare providers, including both obstetricians and specialists in the field relevant to the medication being used.

In your case, you mentioned the use of topical creams, specifically Travogen cream and fusidic acid cream, applied to the glans penis. Generally, topical medications are considered safer than systemic medications during pregnancy, as they are less likely to enter the bloodstream and affect the fetus. However, it is still essential to consult with your healthcare provider regarding the specific ingredients in these creams and their potential effects during pregnancy.
Regarding your wife's menstrual cycle and the timeline of her pregnancy, it is important to note that the absence of a visible gestational sac on an early ultrasound can be normal, especially if the ultrasound was performed very early in the pregnancy. Typically, a gestational sac can be seen around 4 to 5 weeks of gestation. If your wife is around 5 weeks pregnant based on her last menstrual period, it may still be too early to see the sac clearly. It is advisable to follow up with her healthcare provider for further monitoring and possibly a repeat ultrasound in a week or so to assess the development of the pregnancy.

As for the concerns about medication and its effects on the fetus, it is essential to understand the FDA pregnancy categories, which classify medications based on their safety during pregnancy. For instance, medications classified as Category A are considered safe, while those in Category D have evidence of risk to the fetus but may be necessary in certain situations. Topical medications generally fall into a safer category, but it is always best to verify with a healthcare professional.

In summary, while topical medications like Travogen and fusidic acid are generally considered safer during pregnancy, it is crucial to consult with healthcare providers to ensure that they are appropriate for your wife's specific situation. Additionally, the early ultrasound findings should be interpreted in the context of her menstrual cycle and the timing of the ultrasound. Regular follow-ups with her obstetrician will provide the best guidance and reassurance throughout the pregnancy.
