I am the same. Past two years I got pregnant in sept/oct...deer season. I ended up miscarrying twice because I over exerted myself hunting. This time I got pregnant in feb, no hunting and now I am 32 weeks. Coincidence...I think not.
I'm the same way and thought I could do everything but a few months ago I was prego and working on our new house I was helping my husband put in a septic system so I was running around back in forth lifting 60lbs pipes ( not that heavy) but rather way a few days after that I started bleeding went to the ER and they said it was a miscarriage.... Soooo as one hard worker to another take it easy whenever you can..
I am a big time weight lifter. I was told that you can keep going if you can handle it and back off a little as you come closer to your due date. Just be careful!
My family won't let me do anything. And I'm 17 weeks. But ask your doctor.
