Is it implantation Bleeding?

Dij💋 • 🥰🙏🏾❤️

Hey, I need some help. I had unprotected sex 3/26 and on 4/6, I started spotting and have been spotting every since. It’s been 8 days of spotting now. I have faint cramps sometimes but I’m not in pain. My lower back hurts every now and again and my breast pain is very mild. I also have minor headaches. I actually took a pregnancy test 4/7 and it came out neg. I was told I took it way too early. Since I’m still spotting, could I be pregnant? I suppose to come on my period today. I’m still spotting on and off. Help? Please. 😩 plus, I’ve made an appointment to the doctor this coming Thursday. Im just anxious to know.
