Cervical mucas.....

So since joining glow I have been checking my CM quite a bit as I'm in my most fertile days. Myself and my fiancé have made sure we Baby dance every other night. But what I wanted to Know, if your TTC and baby dancing as much as you can, surely when you check your CM some of that may be left over semen from your partner and therefor makes it hard for you to be able to tell what consistency it is etc. sorry for being quite blunt and graphic but I have to ask.......
