Help!! TMI/graphic

Okay, so I miscarried almost three weeks ago now. And a bit. My partner and I started trying again after I stopped bleeding. I ovulated or the day before because of the heavy clearish cm I believe yesterday which is how it is during ovulation for me.. I didn't know it could happen that soon after. Anyways, I've been extremely moody and hungry and have had constant headaches. Lastnight I had a strange discharge that was yellowish no weird odour or pain associated.. this morning I went to the loo and had very very light pink spotting ????

Is it my period starting already? Or IB?
