I started bleeding 3 days before my period, wich is 10/18 but I started my period on 10/15 it wasn't like my usual period started as spotting then when I woke up to us the bathroom it was a lot more. So I was needing to know if this is normal or could I be pregnant? Me and my husband have been trying to conceive for our second one for some time now. And my periods are very irregular.

Id go get checked or do a pregnancy test, especially if your spotting and not a usual period, but I wouldn't worry even if it is just your period mine often come early, sometimes a week early. Still get checked just for your own piece of mind.
