Devanya

hi guys i’m 16+6 days today and my stomach has been feeling very off, i can’t explain the feeling. it’s kind of like cramping or maybe gas pains? they’re not so horrible but strange to me. also i’ve had a knee ache since yesterday. has anyone had anything similar happen around 16/17weeks?? i’m also a FTM so very cautious n worried
