WARNING TMI! Need insight!!

Jocelyn💋 • Have a wonderful life that I have to thank the Lord for❤️ have a son and expecting baby girl🌹
So, found out I'm pregnant, I would be about 4 weeks. Well my period is due around this time and I'm experiencing cramping and light pink blood when I wipe and in my panties it's like a dark brown resish like old blood. Has anyone ever experienced implantation bleeding like this? 
Has anyone experienced this and the pregnancy turn out to be okay? I need insight! I had a MMC 2 months ago and need hope that I won't have another one.
Sorry about the dirty pics ): so sorry about the pics!! Please help!
