Insight Please! :)

Ladies,

Question for you guys. I got a positive OPK around the 13th/14th of the month. I swore I felt preggers (slightly tender breasts/nauseous) and took a couple HPTs around 8 and 9 DPO. I Thought I saw a faint line on the first one but then nothing on the second.

Today, which would be about 10/11 DPO, I’ve had some slight egg white/stretchy CM.

What could be going on here? I don’t normally get this sort of cm before AF (which is due roughly on Tuesday).

Help! Anyone have some insight here??
