Insulin gone bad?

yesterday changed my pod at 4:10. At 6:51 bg was 214. Ate 30 carbs and bolused 3.8 u. at 8:53 380 so I changed my pod and took 5 units by injection. At 10:57 382. Not sure what to do so I go to bed. 12:42 364, not quite awake I bolus 2.7 and a few minutes later change my pod and insulin cuz I figured if a bolus of 5 units didn’t bring me down but 18 then it was probably my insulin, which is almost empty anyway. At 5:03 I was 288 and took 1.85 units and at 8:21 I was 172. This is the first time this has happened to me.

It does happen, and it totally sucks, but you handled it nicely.
