So um I’m a little scared

This app has always been a little off when it comes to tracking my period and ovulation but sometimes it gets it right I just never know when it is. With my first pregnancy I found out 3 days before my missed period. I wasn’t planning or anything I just felt that different/strange so I took a test it was positive 9 months later healthy baby boy. Anyway my period usually comes in the morning the day before the app predicts so I’m just sitting here waiting with no period symptoms except I ate all the sweets and I did that while I was pregnant with my son. I’m freaking out a little but I mean who knows I’m probably just in my head I got a lot going on with my 1 year old, my husband and I are trying to bring God back into our lives, and I’m ending a 17+ year relationship with a friend. So maybe I’m overreacting but I woke knowing I started my period to find out I haven’t yet I’m regular so this is a little crazy for me. I just need to be talked of the ledge I guess I’m not in a position I can just waste money on a negative pregnancy test right now but I’m freaking out!
