Advice ??

renee • Momma to a angel baby 👼🏼💛(3.25.19)

So I ovulated on June 4 I had sex may 29,30 then June 5 on June 12 I started having very light pink spotting , then it turned a little red but still way to light to be my period then it stopped then it turned brown this morning and stopped then to turn pink again could it be implantation or ?? AF?? More importantly could anything be wrong ?? Anymore info on this I’ve been sick but idk if it could be from my sore throat I’ve had a runny nose here and there then backaches and I’ve been tired also my periods are extremely painful and heavy with very bad blood clots and this is nothing like it plus I’d be way to early since I’m suppose to start the 18th of June but started 6 days early ? Any advice and latley I feel like I’m having a upset stomach but like it’s kinda under my belly button area and I keep burp puking ??
