Your blood count will vary slightly over time. Your body is constantly making new cells to replace those that are left or worn out. One of the primary responsibilities of your spleen is to filter old, damaged or defective red blood cells out of your system and break them down. If you happen to have blood drawn at just the right point in this cycle, your manufacturing plant may not have caught up with the recycling facility yet. And yes, your monthly period can temporarily lower your count.
Usually you have to be significantly anemic for it to make you feel tired. In that case, your red count would be significantly below the normal range. "Slightly" low or high counts really don't have a lot of clinical significance.
