Change in migraines

My migraines usually start with aura which lady’s about 20-30 mins then into numbness of my body which usually lasts around 10-20 mins and usually does 2 cycle around the body then goes into the headache. However the past few I’ve had I get a sharp headache pain in my head, then get numbness though the left side of my body for nearly 3 hours. I’ve never had them like this before.
