What do y’all think?

My last AF was Dec 4th I am currently a week late. On Jan 4th I had the lightest spotting that didn’t last but a couple hours, ever since I’ve had no sign of a AF. I am 21 DPO and I’m still getting BFNs. With my daughter I didn’t get my BFP until about 23/24 DPO. Do y’all think I should wait it out and take another home pregnancy test or go to a clinic and get blood test done? I’m really anxious to know already 😫
