Signs??

Izz

So I'm not due on my period until the 30th of this month, me and my boyfriend have had sex every day (sometimes multiple times a day) since I came off my last period. Last night we went ice skating and I got really bad cramp like pains really low in my stomach, like period pains but a day before that when I woke up to go to the toilet I had brown blood like stains in my undies.. could this be implantation???
