How would you manage distal DVT in first trimester of pregnancy?   

Cardiolipin was mildly positive and persistent after 12 weeks (29->28 MPL). No other significant provoking factors. Pt started on LMWH.

What duration would you choose for anticoagulation? Is 3 months sufficient, or would you anticoagulate through the entire pregnancy?
Would you consider this meeting criteria for APLS?
