No, definitely don't put any points into constitution. What Tonya777 said is correct: You use Blood Magic a bit, then normal mana a bit, or the other way around. Any point put into con could have been used to increase spell efficiency instead.
I would normally do this with my mage: Start out with Blood Magic active. Then Blood Wound to control, followed by some AoE and perhaps more control spells. At about half health, I switched off Blood Magic and used Group Heal. Full party health, almost full mana.
If you are truly worried about health, there is a very simple solution. There aren't a lot of good mage rings anyway, but Lifegiver (I think that's the name anyway) from Orzammar increases your health by a HUGE amount. A great ring for any character really.
