How much can i lift while pregnant?

Avoid heavy lifting: No more than an amount where you don't have to strain or bear down (valsalva).

Depends: Depends on your current stage (most "delicate" is during the first trimester) and what your usually lift. If you usually lift a 30-35lb kid regularly, you should be fine maintaining the same level of activity. However, if you tend to be frail in condition, you should probably limit it.
