I think only if exercised to the point of extreme exhaustion would it cause miscarriage. You might still want to talk to your doctor but I think you are okay. Maybe you should take it easy for a the next couple of days since you had such a large day today

Dont go run a 10k marathon but walking around all day is just fine they want you to keep fit from day 1

Yeah, they just don't want you to decide to become a runner after you are pregnant. Ya know, you can do what you did prior to pregnancy with no worries (as long as you don't overdue it) just don't decide to start aerobics now!
Walking around really should be fine, but yeah, talk to your doc about your activity level prior to pregnancy and what if anything you should change now. You should be just fine, but if it will make you feel better then talk to your doc.
If you were pretty active prior to pregnancy then ask your doc about the workout tapes made for pregnant women. You could do those to stay in shape throughout the pregnancy. Well, as much shape as you can stay in during pregnancy, you aren't going to have a six pack or anything!Lol.

I mean I am 41 weeks pregnant and I walk 3 or so miles a day (like around the lake) aside from all the stuff I do in my regular day cleaning the house walking around, grocery shopping, errands, etc...

Dang jess you're 41 weeks? Aren't they gonna induce you or something. I wouldnt be able to take it anymore.. Wow ur a tough lady hehe...

They said by saturday I think this saturday! Sucky huh! Thats 5 days away!

Hope you have the baby soon jess

Dont worry, ive been walking to work the whole time i've been pregnant (like a mile both ways) and i'm now 30 weeks and everything is fine. At 5 weeks your fine...Lots of walking later on might just make you tired. But dont worry....Stress is worse that a little walk.
