Guys, need advice here, few weeks ago, i had intercouse with my gf, its protected, however, my gf said she has this 'Tender, swollen breasts' symptom.
The next day i googled around, some said that its just sign of growth, cause still in young age (20 y.o).

But i still worried cause the other side said that is pregnancy symptom which can come as early as 1-2 weeks after intercouse.

How True are these both.. please help.. cant eat cant sleep cant work right now..
