I have to second Atomic. I have friends that are unable to get pregnant, and my heart is with them. It took us a year to get pregnant (I know for some that is nothing, but for us, it seemed to start taking forever), but I also understand what the origninal poster, as well as many others, are feeling.
I'm 17 weeks pregnant, and for the first 3 months, i felt like I was in a coma all the time. I could barely get out the door to work out, between the heat and the fatigue. I was depressed as well--like I was all ready losing so much of my life. Everyone says "It's all for a good reason", and I agree, but it has been such a shift in personality and how I view myself.
Now that I can run again, it's still taking some getting used to. I am not as fast, I don't go as far, and I walk a lot more, but I get out there and keep going. I get so many "tsk tsk's" about my running, even from highly active people. I even stopped going to my midwife because she was a) so behind the times on the research on heart rate and RPEs for pregnant women (the old 140 BPM no longer is the norm) and b) so unsupportive of my activity. I know my body better now than I ever did before I started running a few years ago, and I know when I need to stop. Yet, she wouldn't let up on it. My doctors (both my family doc and my OB) are so supportive, it's amazing.
SO.....short story long, I know how you feel as a pregnant runner. I'm learning to accept the differences, and the depression has lifted as my running has been able to pick up a little again. I figure if I can run 2 days a week and walk 2-3 times per week, it works for me, gives me enough mind clearing time, and keep sme happy (which I figure makes baby happy too!)
Girls, we will make it. In a year, we'll be running again--with families in tow, but running nonetheless. Keep it up ladies--we can all do this!
