Short but sweet

Hi, me and my partner have been TTC for a year and a half now, this month we went all out 😂 used all the fertility lubes, vitamins, etc etc. Well before my period was due I took a preg test nearly everyday (negative) then I came on a day late and it lasted 2 days and extremely lighter than my usual period & also the colour was different, I'm now fully period free this should be day 3 of my period, do I test or do we think there's not a chance 😬😬 please help!! ☹️
