To prevent your period from starting, you should take the blue triphasil tablet from the pack. By taking this tablet, your body is prevented from releasing the egg, which can be the reason behind the delay of your period. The scenario becomes bright when you have a special event or a trip planned, and you don't want your period to come. Triphasil is safe to use for this purpose, but you should always follow the instructions and take the pills every day at the same time.

Experiencing a missed period, back pain, leg pain, and vaginal pain could indicate various underlying causes. Consult with a hyour doctor for an accurate diagnosis and appropriate treatment.
