Hi. I Am A 28 Year Old Female. I'm Experiencing

Hi. I am a 28 year old female. I'm experiencing random bruising on my upper and lower legs. Some of the bruises are small dot bruises, and others are very large in size. I do not recall trauma with any of them, and they do not hurt when I push on them. A couple of them have been there for several weeks, a new one appeared this morning. My PCP ordered a CBC which was normal. He looked at the bruises today, and stated that there are no lumps or bumps within them. He thinks I must just bruise easily and do not recall the trauma. I just wanted a second opinion because it is so odd, and I wasn't sure where to start. Thank you in advance.
