I'm going crazy !

So I like to pay attention to my cycle and when it comes and im constantly checking if It's normal . & I'm 11 days late for my period . I'm going crazy . I have sore breasts , occasional nausea , some light cramping , I'm super bloated and I feel pressure on my lower abdomen . I've only taken one hpt on the 8th day of being late and it was a - . Me & my SO sometimes use a Condom but mostly just use the withdrawal method . And I can only think of one day where I could've gotten pregnant . We were both drunk and I don't remember him pulling out . And I checked and that day happened to be my first day of ovulation . OOPS . I'm going to take another test once I'm 2 weeks late . But has or is anyone in the same situation I'm in and ended up being pregnant ? I feel like I am . I can't explain it .
