I think it's really normal to have shortness of breath in pregnancy. With my second, I could barely breathe by the end of pregnancy. I remember it started "earlier" than I would have thought as well. I carried him really high in my lungs though, so I don't know if that affected things. I also had lower blood pressure with him than I do this time. I am typically rather low, but am running a bit closer to "normal" this pregnancy.
I have gained a lot of weight so far. I am up by 15lbs if I count my "start" weight as my normal weight before the "crash LE diet." I don't think i really lost weight so much as fluids on that 2-week tryst with it. So I count my "start" by where I was maintaining before the month we conceived. But obviously if you add in the 10lbs I lost immediately prior to conception, I am up 25lbs!! Holy cow ;) But I generally gain more in the beginning of pregnancy versus the end. At least that was true with my boys. I gather that I will gain right around 30lbs this pregnancy, which is about what I gained with my last child. My first was a special case, I was much larger to start out with and never gained anything with him.
Out of curiosity, those who lose pregnancy weight while nursing...I have heard it is more common to lose the weight while nursing when you are an "apple" body shape or a "metamorph" body shape (apple means carrying more weight up above your pelvis, metamorph means carrying equal amounts above and below). I heard that women who are "pear" shaped (carrying more weight in the thighs and legs than anywhere else) are the ones who have a hard time losing weight while nursing. I am not sure if it is true at all. But it seems that among the friend group we were talking about it with (five of us), it does seem to hold some truth. I am an apple and drop weight like mad when nursing (with DS1 I lost 50lbs in the first 4 months of his life, with DS2 I lost all of the 30lbs that I gained in pregnancy and an additional 5lbs by 4 months in). But two of the ladies in the group actually hold all of their weight or only lose a bit when nursing and both have a significant body shape difference from the rest of us. Anyone else finding this to be more than hearsay? Or was it a coincidence?
