CM question. A bit puzzled

Saray
I ovulated last Monday and we BD the day and next day. We are TTC. 
​After that my CM got dried and like creamy but light. Today I went to bathroom and checked and even though light as far as the amount it was clear and like egg whites. How come? Could that mean I'm pregnant? Or am I ovulating again?? I don't have any other symtoms of ovulation. My sex drive has decreased as it usually does after ovulating. I have painfull breasts. But that can be PMS. Help!
