If you are on your period but:

·       Feel well, and

·       Do not have very heavy bleeding or severe cramps,

you may still be able to donate, as long as your hemoglobin is high enough. Some women prefer to avoid donating on their heaviest days just to reduce the chance of feeling weak.

If you are feeling unwell for any reason (fever, infection, severe headache, vomiting, diarrhea), you should not donate that day. Wait until you are fully recovered and have finished any course of antibiotics, then come back.
