Help!

Ive been on birth control since december and lately i havent felt good....wicked headaches sore boobs darker nipples little nausea that comes and goes extremely tired despite going to bed early. I don't know when my period would be because I skipped my sugar pills and started a new pack this month but according to this app it would have been jan 21. I decided after everyone joking saying birth control probably failed I peed on a stick Thursday. I got an extremely faint line like had to stare hard but it was there. We went on vacation so I peed on another one this morning and it was faint but way easier to see and darker. What does this mean and what do I do 😭
