So I have a sploty, Brown birthmark on my upper thigh, and I just remembered that I wasn?t born with it. So I researched it and birthmarks can develop but, up to a month after birth. But the birthmark I have I got when I was about three months old. My mom told me that she , someone who went to medical school, was scared and didn?t what it was or where it came. When I first got it it was purple and blue like a bruise, but then after a little while it turned brown. And I?m confused as to why this happened, so if anyone knows or had an idea please let me know.
