Can restarting my birth control be confused with symptoms of pregnancy?

Patient: I stopped taking my birth control for a month (due to me being unable to afford it), and now I have restarted it and am on my second week. However, I noticed I’m super bloated, and my breasts are really sore, and that normally doesn’t happen until I’m about to get my period. I have had sex, but he didnt orgasm or ejaculate. Are these symptoms from the restarting the pill or could I possibly be pregnant?
