Any Pregnant mums here?

Yes!! I'm 13 weeks pregnant today and have gained about 4 pounds so far. I just rejoined MFP today because I need to reel in my eating habits and get some exercise in now that I'm not sleeping all day like I did in the first trimester. I'm 38 years old, this is my second child, I'm 5'6" and now 164#. I really don't want to gain more than about 15# more and only if necessary. My BMI was like 25.1, which is just overweight when I got pregnant. Well, that's my life story (haha) so maybe we could be MFP friends because I can't relate to the "losing weight" crowd right now.
