Random Spotting 11 weeks PP?

Cheyenne • I an 27 and I have a 3 year old boy, 6 year old boy, a 7 year old little girl, and 16 month old little girl
So I am 11 weeks pp and I have not had any bleeding since 2 weeks pp and I assumed the next time I started bleeding it would be a full period. Well two days ago I started lightly spotting and I thought it was my period. Well it completely stopped, and then today I have spotted a little bit. Has this happened to anyone else. I also am TTC again.
