slippy - i know how you are feeling. i had gained a lot of fitness before falling pg, then in the first tri, i just couldnt do anything, for all the reasons you mentioned.

but dont despair. you should feel so much better once you get into second tri. i have been walking and swimming every day since about 18 weeks, and although it is a lot less intense than before pg, i really feel i have regained a lot of my former fitness, and plan to get back to how i was later on too.

just try to rest and not worry about it too much, your body will tell you when it is ready to start picking up again. but i cant recommend swimming enough - it feels so good, especially when you start to get heavy and uncomfortable,

all the best,

Linda
