Faint positive test , cramps & brown spotting. HELP

Lauren • Previous miscarriage , one year old.
Okay , so I am kind of confused/ scaring myself. My period isn't suppose to start for another week, but two agos something told me I should take a test I got a pretty faint line considering it's so early. Two days later (today) I have been experiencing what feel like period cramps with brownish spotting/discharge. Has anyone experienced this? I'm not sure maybe chemical pregnany or if it's implantation spotting because it is so early. Let me know if anyone has any similar experiences or advice. 
Also, I had a silent misscarriage two years ago when I was in my third month where I didn't experience any "normal" misscarrying symptoms so having cramps and spotting is all new to me. Thank you ladies. ❤️
