Trying to conceive and period arrived 5 days early and is extremely light and off and on Hpt was negative and never been early or late to get period before could that be sign of pregnancy?

It could be implantation bleeding. I got a very faint positive the day after I missed my period and a dark positive 4 days after, I tested the day of my period and it was negative. Wait until your period is actually due and then test. Good luck!
