confused? any similar stories???

Txt one year and a few months. Two MC's (months ago) 
I'm seeing an infertility doctor and we can't do any tests till I start my period....well it hasn't come yet. I'm 12-13DPO but usually by this time I've had my period...
I've had pink CM yesterday, this morning light brown cm on my tissue paper (like a water stain) and I took a pregnancy test and it was negative...... oh the confusion. I've just emailed my doctor so we'll see what he says.
Also been fighting a massive migraine. So I feel like I'm in Limbo right now 😬
