10dpo - not sure what to think? (TMI warning)

Alrighty, so I'm going on 3 years post op RNY and almost a year post op belt lipectomy with abdominoplasty. O'd on 5th. 

Incoming TMI

didnt think much of the sore bbs or extreme moodiness until 2 days ago (8dpo) I woke up with HORRID diarrhea - like almost dumping syndrome. No new foods though - and I don't dump unless I'm dumb and grab a candy bar. 

Yesterday I had a glass of milk and some toast (2% milk as always) ..I always have this - but this time it shot my blood sugar up to 172!!! What the heck?!  Extremely thirsty - moody beyond belief even for me - I'm not due for AF until 22nd (next saturday) 

Does it sound like I need to test later in the week to anyone else?

The only time I have ever had a problem with blood sugars post op is while pregnant! Might wanna test!
Also, milk is a huge problem for me now!

I'm going to be getting either 1% or fat free tonight to see if that helps. If it weren't for milk I'd get like ..NO protein in. Took a test today but not first morning urine.  Gonna take one tomorrow if still bfn then I'll wait till wed. or thursday. I have to know asap lol mother nature doesn't care though xD
