Choosing Between Lump Sum and Weekly DCA VTI

I have savings targeted mainly for VTI investments (along with VXUS and IAU). My DCA plan is to invest weekly on Mondays until early next year. However, based on my past DCA experience since last April (when I officially entered the market), I regret not doing a lump sum investment on day 1.. Since this is savings I don't need for my daily life right now, should I just lump sum it since the market is dipping today? I’m an anxious person in general but I can sleep fine with a lump sum investment
