Pregnancy symptom?

So I only have been checking my CM for the last 2 weeks to see when I was ovulating and if the CM matched up with my opk testing. It has. But... I have been reading the book What to expect BEFORE your expecting. It tells me if your CM stays creamy and thick AFTER ovulation and stays that way that it’s most likely possible I have conceived... I’m really hoping so but I took a test last night and it came out negative even though it is very early for testing.. so I’m holding out until Saturday or Sunday to test again. I want to know anyone who has recently conceived... of you were checking your CM what did you have? I want to see how truthful this book is. Fingers crossed!!

Plus my breasts are tender but more in the nipple area and I have some slight cramping but I keep thinking it’s because I constantly thinking about being pregnant that I’m just making this all up in my head. I want more than anything to be pregnant already!!
