implantation bleeding

Nikki
I've never had it with my first son or my last pregnancy...but my af is due in 4 days according to glow & my SO and I have done the deed every night since last af bc we are determined... I just went to the bathroom and wiped and they was a huge snot glob with pinkish color and then nothing else...could this be implantation? I also tested this am the test is the bottom one from this am...ahh!
