Brief Answer:
You are at risk of thrombosis so you need prophylactic anticoagulant.

Detailed Answer:
Hi, dear
I have gone through your question. I can understand your concern.
Your lupus like inhibitor test is positive and you also have family history of thrombotic events.

You should take prophylactic treatment with anticoagulant. Aspirin is good option. It has protective role in clot prevention. More over Krill oil is also helpful. It contain polyunsaturated fatty acids. It has also anti oxidant effect.

No need to worry. Just be relaxed. Continue with aspirin as per your doctor's advice.

Brief Answer:
Aspirin is sufficient at this stage.

Detailed Answer:
Hi, dear
I have gone through your question. I can understand your concern. You have family history of PE. You are tested positive with lupus like inhibitors. So you need prophylactic anticoagulant therapy. Low dose aspirin is sufficient to prevent thrombotic events. No need of warferin at this stage.

Continue with aspirin and krill oil.
