Now I am very scared

Dianna

So, I made a post earlier this week but it basically said that I was lost as to what was happening with me. My OPK was positive but all throughout my fertile window I was dry with hardly any CM at all, and the little I had was very creamy. Even when usually I secrete the day after BD, was not coming out. Well last night and again tonight a huge blob of CM came out and when I went to inspect it, it was creamy, runny and yellow. Now I am terrified that not only am I not pregnant this month, but that I may have something that will further delay the process this month. I am seeing the doctor tomorrow (I already had an appointment from last week luckily), but do you think this means I have an infection or what do you guys think it could be?
