Noticed something off after starting birth control

Two months into a new prescription and suddenly my thigh feels tender and weirdly warm in one spot. Doctor mentioned clot risk during my consultation but didn't elaborate much. Can someone walk me through the signs of deep vein thrombosis? Just want to know when to actually panic.

That’s actually worth paying attention to. I had a scare like that after a long trip - one calf felt warm, kinda sore, and slightly swollen. Turned out not to be a clot, but the doc said the combo of warmth, tenderness, swelling, and sometimes redness (usually in one leg) are the main warning signs. If it starts hurting more or you notice swelling spreading, don’t wait it out. This breakdown helped me understand it better: early stage blood clot in leg symptoms vs muscle cramp - simple and clear.
