Late and really confused/worried


I usually have perfect periods and have for years. Last month I started ttc and I had a lot of spotting and then a couple days of AF. This month I am already 6 days late. I tested on day 2 and BFN. I know I'm out but I'm just very confused. Did ttc mess up anyone else's period? Or do you think it could be a bigger issue? I feel so worried 😭
