Don't know where to put this topic.

I am 28 days pp today, and please no judgement. But I thought I was starting my period.. and this morning I had spotting 2 times and never again. It was gone. Theres no bleeding nothing anymore from giving birth. Does this sound like I could be pregnant again? I know i/we should've waited. But does this possibly sound like IB? Had it when I thought I was starting my period before I found out I was pregnant. And on top of that I'm having the white discharge. Like I had while I was pg. Please again no judgement only advise/tips please.
