Very Thick white cottage like discharge after period withno itch or odor.?

Lately I have noticed whenever I finish my period and have sex I usually get this thick white discharge a day or so later. I have been usuing a product called rephresh also and notice it more after the 1st day I use it as well. The discharge does not smell and there is no itch. It is kind of worrying me. I finished my period a week ago and today the discharge was white very thick like and faintly pink almost like light blood. Can someone let me know if this should be a concern???
