Postpartum period or implantation bleeding ....

Hey ladies

Okay so I’m almost 9 weeks postpartum and about 2 today’s ago I started light spotting. It’s nothing like my periods before I only have blood when I wipe and occasionally if I don’t have to go to the bathroom for a while I’ll have a few spots of blood on my panty liner. Sometimes is dark almost brown blood or it varies to bright pinkish red. My and my husband have had sex at least 5+ times unprotected since I’ve been cleared by my doctor, we are trying for our 3rd. Yes I know what some of you are thinking but we want our children close in age. My first was born in January of 2016 and my second in December of 2017. I’m only 24 so my pregnancy’s haven’t been too rough. Anyway off topic do you ladies think this could be the start of my period or implantation? Or maybe just more postpartum bleeding ? Oh I’m also EBF my daughter. Let me know what you think gals 🤗
