Hello,
Thanks for posting your query.
It is unlikely that your three year old daughter has swallowed any hormonal pills without the aid of water. These pills are bitter most of the times. Even if the child takes them, she is most likely to spit these out.
If at all she has consumed a few pills she might get an irregular spotting from her vagina which is harmless and is self limiting in nature.
No specific treatment is usually needed.
You need to be more careful regarding storing your medicines properly to avoid such incidences in future.
Hope this answers your query. I will be glad to answer the follow up queries that you have.
Please accept my answer in case you do not have further queries.
Wishing you good health.
Regards.
