Seriously what's going on?

So I'm having all symptoms: 
Light cramps
Cravings for sweets and salty 
+ appetite 
Sore boobs
Extremely tired
Peeing more frequent 
Also looked like I was having implantation bleeding cause it was dark dark brown looking and only spots .
But ... My period is supposed to start in 9 days 
Took a test and it was positive with a faint line ,& took 2 more (not same day and they were negative. Am I testing to soon? Also here is when I had intercourse on my fertile days. If it helps at all. 
Please help:/
