Exercise?

So before in was pregnant, I went to the gym religiously 3 days a week no matter what along with random exercise like hiking or whatever on the weekends. Ugh! Now Im struggling with being so tired all the time that I go when I can but its not often... last week is was once. The week before that, none but got a good walk in. Its just hard to get any motivation. Not to mention my diet is outta control! I'm 10 weeks... I'm just holding out for that 12 weeks. I'm hoping to get a handle on it after that! Lol. God bless all you ladies!!
