Weebles wobble but they don't fall down!!!!

So, I'm about 27 weeks now! The Lord has blessed me during this pregnancy and I am grateful for it! I have not been sick nor have I had many difficulties. Well, I mean, I have had some "back pain"......translation "i need a back rub!" but that is about it. A few headaches here and there and indigestion but as for MAJOR issues, none here. I must give praise to the Lord....I think He spared me from those "issues" due to my low tolerance for pain. Yeah, we aren't thinking about the whole "how does this baby arrive?". Well, I have been trying to continue to do some type of athletic exercise but some days I just "forget". (I have been told pregnancy makes you forgetful at times :) ) This particular morning I felt like one of those weeble wobbles. I was trying to swim and something was not working for me! When I would turn to breathe I felt my whole body rolling to one side - almost like it wasn't going to turn back over. I was thinking I would just roll right onto my back. I would take a breath and then back over....then to the other side! I am sure the lifeguard on duty was finding this sight something to chuckle about! But after it was all said and done, I got a great workout!!
