Advice needed

Selah

AF came on June 14 and ended three days later, ( normal for me since I’m on the pill) but recently my nipples have became super sensitive, I’m starting to get some bumps around my areola, my breasts are a bit swole, and I get sporadic sharp breast pains especially when I sleep on my stomach. I am active and have not used any form of contraceptives except birth control pills. Are these early pregnancy signs? I don’t usually get them.
