Yes, there is a possibility of pregnancy since you had unprotected sex during your fertile window. Dydrogesterone and B Long F (pyridoxine and folic acid) support your cycle and overall health but do not prevent pregnancy. Given your usual 35-day cycle and last period on February 15, your next period would normally be expected around March 22. If your period is delayed past this date, I gently recommend taking a home pregnancy test for clarity. Please stay relaxed, and feel free to consult your gynecologist to discuss your next steps.

Yes, it is generally safe to take your prescribed vitamins and B Long (pyridoxine) tablets. Vitamin B6 is frequently recommended to help regulate hormones and ease the breast tenderness that peaks before your period. Please take them exactly as your doctor prescribed. To further ease the discomfort, you might also find wearing a supportive sports bra and reducing caffeine helpful. If the pain changes or worsens, please follow up with your healthcare provider.

Folic acid is incredibly important in these early weeks to support your baby's development. While a standard daily dose is usually 400 micrograms (0.4 mg), a higher dose like 5 mg is safe and often prescribed for specific medical reasons. Taking 5 mg is not harmful to you or your baby, but it is best to discuss your specific needs with your doctor or midwife. They can help you determine if you need this higher dose or if a standard prenatal vitamin is the right fit for you.

B long is a brand of Pyridoxine, also known as Vitamin B6. While it is true that Vitamin B6 is sometimes used to support cardiovascular health, it is also very commonly recommended to help relieve the tenderness and swelling associated with breast cysts. It helps by naturally regulating fluid balance and hormones in your body. Please rest assured that using it for this purpose is quite common and safe. I highly recommend speaking with your doctor to confirm the right dosage for your specific needs.
