One day late and only BFN?


I was expected to get my period today and honestly I’ve been feeling a lot of pregnancy symptoms but have gotten 3 BFN tests. One at 9 DPO (not surprising) one at 10 DPO and one today at 12DPO and one day late.

Idk if I wasn’t so nauseous, ditzy, tired, among some others I think I would just chalk it up to stress but I’m usually very regular. Like on time or a day early so it’s very weird for me to be late at all. Any one else not get a BFP until later? Or is this just wishful thinking?
