I need an answer

I always get my period on time or a day late but never early! I have had cramps the past week or two. And yes I am trying to concieve. I ovulated on the 16. Period due October 2/3. But today I wake up and pee and there is a little light red blood almost orange it's so light when I whiped. Not a full on period. I don't know if it's the rigt timeline for implantation. I'm afraid I won't be pregnant. Any opinions??
