pregnant ?

hi guys sooo i on BC pills but i miss them a lot and i’m trying to get better at taking it but i want to get off of it and start trying within the next few months. i’m currently 3 days late, and on my 22 cycle day i spotted brown in my panties but it was only once . i’ve been having slight slight cramps and back pain but what’s weird is my boobs. my boobs have been EXTREMELY sore for about 4 days and super veniny and itchy!!! my boobs tend to be a little sore before my period but never this sore. also i usually get very bad acne before period n my acne was bad about a week ago but now my skin is fine. which is weird bc even if i was going to get my period rn my boobs and acne would be acting up at least the same week?? when should i test?
