When speaking to my Dr last friday, she told me that I should not be doing any kind of heavy lifting at all, as with my past history, she says that the lifting puts strain on your abdominal muscles, and too much strain can start a miscarraige. She worked overseas around asia in her previous job, and says all to commonly, she saw women carrying those baskets on their heads etc, and they miscarry on the road from the strain.
On the other hand, she also told me to take metamucil (sp?) to help avoid constipation, as she says straining hard to pass a motion, can start bleeding that can lead to a miscarraige also.
So my advice,,,,,,,dont lift what is not absolutely necessary!!
