My period is late😩

I use glow to track my periods and fertility to prevent pregnancy. I want kids one day but I don't think today is the day!!! I thought I had irregular ones until I started tracking it then I just realized I'm crazy . My bf and I have been together 3 yrs I got pregnant with in out first year but miscarried. We were careless and just flat out did not use protection . Now we use the pull out condoms and sometime bc but bc can be a little rough for me anyway we barely had sex !! And he pulled out! I'm really nervous but I know if u stress that can make u miss too. So I am over here trying not to stress about stressing out ! I felt nauseous but I haven't thrown up I got headaches my boobs hurt and feeI so sleepy. I have also been extremely emotional this post will probably make me cry I get mad at my bf so easy then bust into tears but then I'm happy again because I stuffed my face with pizza.
