Pp period???

Rachelle

I am 6 months, almost 7 months pp and have no had a period. I did start spotting around aug 7 and then had a very positive lh surge for ovulation on the 25th. I have no been having some more spotting (i say spotting because i dont need a pad) brownish to red. Could this be my pp period. Having some cramping. We have been intimate since 8 weeks pp, abd was on 8/24. Can someone let me know. I don't go to my ob until 9/20.
