i h8 hormones

i had protected sex (condom & BC) in August. I got my period right when i was supposed to and there was nothing weird about it- pretty heavy actually & for 6 days. I’ve been on my BC for almost a year now so i’m confused about these symptoms. I have not had sex since the end of my most recent period. I am currently about 2 weeks away from my next period but i’m experiencing sore boobs & a little bit of nausea. I’m quite an anxious person- so please be kind but i’m not pregnant right? Could i be reacting different to the pill all of a sudden? Stress? Has anyone felt this way before? I just need someone to help me confirm i’m not pregnant. The picture is from the first day of my period- it got heavier from here!
