Cervical Mucus During Pregnancy

Mari • Pregnant with our first! ❤️
Hi ladies! A question for you:
​What was your CM like in the first few weeks of your pregnancy? How many DPO were you when you noticed any? I don't think I'm pregnant, but my CM is derfinitely a little different today. AF is due next week, but I don't know how many DPO I am, as this is the first month I am not tracking temps/OPKs. 
​Thanks for your help!
