HELP! I need to know if I could be pregnant

Idk if I'm losing it or what!!?? My husband and I had date night on Feb 10th he went in me twice that same night. I was already schedule to start that following week. I was at 3% chance of getting pregnant. I started my period a week later as expected, but only went normal for 3-4 days the fifth day was pretty much the lightest I've seen it. I usually go 7 days, I ended my period about two days earlier then usual. My question is do y'all think I'm pregnant, and when would be the earliest and best time to test.  Annnd to add, I'm constantly peeing like no other, idk if it's my diet or from a possible pregnancy
