A gain?!

I weighed in on Thursday and then again on Friday, hoping to see a different number.  Nope!  I was disappointed and mad to see 236.2 lbs.  WTF?!  I've been consistently working out at least 3 days a week since the beginning of December, actually started back working out in November.  The last three weeks I've been focusing on what I'm eating and with portion control.  I don't get it!  I am about to throw in the towel but I haven't.

 I got in another nice 5k this morning, even had company for a while!  The sun was out but it was a bit chilly, a great day for a run!  I did the 2 min run (a few times even did 3 min) and walk 1 min.  My legs are now killing me.

I'm at a loss as to what I should do next.  Any suggestions?  Any readers still out there?!
