My layer of SLOW!!! (is annoying)

So yes I do realize that weight gain is inevitable while I'm pregnant... but it doesn't mean I have to like it!!!  You see I worked my ass off losing all the previous baby weight, and I know what I'm in for to lose every extra pound I gain.  So a little dark secret of mine is that I am obsessed with online pregnancy weight trackers. 

Here are a few that I randomly use:

I never did this with the other 3 pregnancies, I didn't beat myself up.  But for the last two day's I have been punishing myself!!!  I can barely walk (which will pass of course).  But yesterday I did body pump then attack and tonight I did combat then body pump.  I have been eating tons of protein and trying to cut back on sugar, eating as clean as possible.  I'm pretty sure I can maintain it until the weekend of course.  But according to my data and calculations I am about 2-4 lbs overweight for week 17.  So this is what I'm talking about.. my layer of slow.  It's annoying and I want it gone, it is sucking my energy away, especially with all this heat that we are getting, and it looks icky!  Of course I realize that said layer of slow is not going anywhere, it is very possibly going to get even slower!!!  ahkkkk...  The thing is I know, what I should know, but for some reason my mind is fighting it...  With this being my 4th pregnancy I wanted to re-write the rules, I wanted to be just a belly without all the extra "slowness" or "insulation" however you look at it...  But I just don't think my body is cooperating with my idea's.  I'm struggling because being pregnant I allow myself some "extra's" but at the same time, I look at the results and I think logically, those extra's are too much so I should just go back to the "eat clean" basics.  No extra's (unless it's Saturday or Sunday)

Well if this wasn't a rant... I'm not sure what is..

Ps.. Doesn't the baby look like an alien?
