One thought on knowing your blood type... There is much testimony here from people who thought they knew their blood type, relying on misinformation or just not remembering correctly.
If you are not absolutely sure from your own experiences dealing with medical issues or from being a blood donor, you may want to test yourself. The easiest way is to donate blood. Not the fastest, but it doesn't cost anything, and you help a worthy cause. You will learn your Rh factor, too.
