Implantation?? TMI

Holly • I am a stay at home mommy with a 4 yr old little boy named Deavan. Currently TTC for #2 with the love of my life!
So I am now 4 days late in receiving AF.. O'd on the 25th and have had nothing but cramps and thick stretchy yellow tinted CM. until this last night when it seemed to have a brownish tint. Any input? Am I just wishing too much? Btw no signs of AF gracing me with her monthly bs. 😉😋
