Hi, Thanks for using HCM.
Your delay in periods could be due to stress
from infection, need not have to worry for it. Wait for few more days, periods may start normally. If it doesn't happens ,Get UPT once again, after ruling out pregnancy
, you can take progesterone
preparation for few days, which on stopping medication causes bleeding as withdrawal bleeding.
Hope I answered your question. Consult your doctor for further examination and management.
Feel free to ask me if you have any further queries.
Wish you good health. Take care.
