Does anyone know?

So for starters i am 16 weeks pregnant and i dont know if i should be concerned and get a second opinion, but i normally always shave my downstairs and never had a problem well recently ive been getting these blisters that come to a white head and when they pop a type of puss comes out but its not a zit it has the feel and look of a blister i asked my obgyn he looked and said it was nothing to worry about but i have also been receiving what seems to be small abcesses on my leg to, should i be concerned? Has anyone heard of or experienced this? I had asked my obgyn to do some blood work just to make sure everything was ok and he said it wasnt necessary even after i had mentioned my daughter has mrsa its dormant now but i just wonder if i may have gotten it some how? advice would help please no negative comments.
