Finally pumping!

Amy- I am now pumping with a pink Minimed 522 and it is fabulous although I just started yesterday :) but...well. My blood sugar has been REALLY low. I will tell you my settings and then my bg's so far and you can decide for yourself! Okay first of all, my flat basal rate is
0.35
My I/C ratio is 1/20
and my IS is 1/75.
Which seems all rather low for an 18 year old girl, right? So I was expecting highs! Well...take a look at my sugars so far!

So I'm not wild about all these lows...they scare me a lot!
