I went to donate blood today, but was rejected because my hemoglobin count was at 12/1 the first test, and then 11.1 the second time. Unrelated to getting rejected, but noted was my blood pressure was very low at 100/38. I'm normally in the 60-70 range for blood pressure when I get check ups. Any reason why both my hemoglobin and blood pressure would be low?
I'm a female, and my cycle starts in a week. I heard that being on or just finishing it lowers hemoglobin, but like I said, mine starts next week. And The administrator said not to worry about, so I'm not terribly concerned, just curious. Thank you!
