So you missed 1 day, and then took one pill a day for a week and then stopped, right?
Well, if you had sex in that week, I would say it's unlikely that you got pregnant because you were still taking pills. However, there is a chance because you never took that Tuesday one which you were supposed to. But you know that.
If you had sex after that week, with no pills, there is definitely a chance that you are pregnant. You should test.
However, you can't use your symptoms to determine if you are pregnant, especially (like you said) because they are so similar to symptoms we have at other times (like pms or coming off bc). I wouldn't worry that these symptoms mean you are pregnant necessarily.
I would just wait and test. Good luck.
