What is a obgyn that you went to. If you still have the spot, We can't view the pictures the links didn't work, then I suggest you get a new doctor and don't play around with this. GOOD LUCK!

Hrm.. see if they work now?
It is a superficial mark? In other words, is it just on the surface of the skin or is there a lump or thickening underneath? Has the mark changed at all during the past four months? Either way, a new spot that appears such as yours needs follow up with a GOOD doctor. It could be nothing at all, but you can't gamble with your health. Getting yourself to a new doctor asap should be your top priority.
I couldn't tell by the photo, but is there a center to it or any raised, lighter area in the middle? I had a similar marking one time, but it did not last as long as yours. Mine turned out to be an ingrown hair. Weird, I never saw where the root even was. I squeezed on it and it bruised more and leaked out the old blood before I actually saw that a small hair was under there. I would NOT recommend that you do this. Try a dermatologist, they may have to lance it if that is what it is. Best wishes.
