Ladies help me

Carla • Hello :) 21 and my husband is 37, Finally got pregnant with baby number 1 :) Any help would be great :)
Hey ladies, 
I was inseminated on Monday just gone, and my CM has changed, normally at this stage through my cycle it's watery white, but now it's changed to a thick chalk white but doesn't smell? I've been to the doctors and got checked for infections but I'm clear. Can any body help me ??
