I've been very careful when it comes to sex and always taken my BC pills on time, but I've been super stressed lately and I'm going onto my 3rd sugar pill and still no period. I honestly don't see how I can be pregnant because of my safety plus being on the pill but idk if this is dumb to ask but can your period be late because of stress or is my body just being weird or idk I always freak out when it's late
