Mene karib ek mahine pehle apne bf ke sath 2 3 time sex kiya tha aur safe sex hi kiya tha pr mere periods nahi aaye h 2 month se..muze regular periods nahi aate h.. aur ab kuch dino se muze ajib feel ho raha h tabiyat kharab si ho rahi h aur dar bhi lag raha h ki kahi ye pregnancy ke symptoms toh nhi h ? Safe sex krne ke baad bhi ho sakta h kya esa
