Something’s not right ....

So I’ve been on birth control (the pill) for a year and a half now consistently. I’ve heard of girls getting pregnant on the pill but almost all of the ones I knew didn’t take it properly ... anyway. I hade my period July 24-30. So according to my calendar I should be ovulating this week if I even did. Y’all... yesterday I cried over a frozen meal. I never cry ever over anything not even funerals .... I cried because my boyfriend didn’t put my frozen meal in the freezer and it was ruined (I realize how ridiculous this is!) then I took a nap 2 hours after I woke up ... cried because he touched me. I seriously don’t know what’s going on with me ... is it possible I could be pregnant? Or is it just something with my hormones?
