I have been having numbness in my left thigh since about 15 weeks pregnant now 24+6. Saw the midwife today who said prob just baby on nerves which I thought too so have never worried. When I got home my midwife called and said I need to go to DVT clinic tomorrow at 1pm incase I have a clot. She said it's unlikely but needs to be checked. I panic anyway so this will be a sleepless night 
I have been on asprin since 12 weeks and u really didn't think it would be anything to worry about. I have no other DVT symptoms!
Has anyone ever had the numbness and it's been ok?
