Pregnant 👶🏽 or Paranoid 🤔

Shelby
So recently my boyfriend (25) and I (17) started TTC and we have had sex everyday this month since my period ended on the 10th. But I've been experiencing bad joint pain in my knees and hips and abdominal pain. Also I've started gaining a little weight. Idk if I'm jus trippin or if I'm having early pregnancy symptoms. Anyone understands what I'm talkin about?
