Possible blood clot?

So I just woke up to make my daughter a bottle and I noticed that my leg is tender in one spot. It feels kinda like a bruise but I honestly don't remember hitting my leg. I have a family history of blood clotting (my dad, great grandma, great Aunt). I was tested while I was pregnant for the clothing disorder my dad has and it was negative. I have also been on the mini pill for almost a month but I thought with the mini pill my risk of blood clots was extremely low since it is progesterone only. Is this something I should let sit for a few days and see if it goes away and if not then go to the doctor? Also, can my regular doctor examine it or do I have to go to the er? I'm freaking out right now. I don't want to die and miss my baby growing up. Any advice is appreciated. I attached a picture of the spot.
