Good on you hun!

Make excersise something fun that you do not a chore, you will be more likely to keep up with it if you have fun.

Also don't beat yourself up if you don't do anything one day, i think having lazy days is normal and usually something we do need.

I can totally relate to being comfortable standing in my underwear infront of my DP. I've never felt comfortable even though i was not always big i just lack self confidence but after bub id like to try and get back into shape.
