It sounds as though it's OK but you still need to get it checked out by your GP. Meanwhile, take a photo with a ruler or tape measure next to it so you can see the size. The GP may want a photo sending to them if they can't see you face to face. They may ask you to monitor it for a few weeks, taking similar photos every 2 weeks to see if it is actually growing.

Good luck and please let us know how you get on,
