Spike after hypo symptoms?

Mandi 😈💀 • Expecting #2 August '15!
Twice this past week I have had low blood sugar symptoms with low-ish numbers, 70 and 72, and have happened to eat white rice, shrimp tempura rolls and white rice with chicken, immediately after the lows. Both times I have had blood sugar spikes, 137 and 153, at my 1 hour test. I happen to not have had any other hypo symptoms, and I also haven't eaten rice any other time since I started testing! I am trying to figure out if it's the rice, or if it's possible that I got a spike because I was low. I will try the rice again when I'm not low to see if it happens again to make certain, but has anyone had low sugars then eaten and had a spike after? Thanks :-)
