Hi, i'm 33 years old,5'4" feet, 54 kg, i'm a G2P0 (0010) pregnant uterine 20 weeks AOG. On my first trimester , i was diagnosed to have placenta previa totalis but had no bleeding and my last ultrasound was at 16 weeks AOG, it read placenta posterior grade 1 , low lying, the placenta is 3.3 cm away from the internal cervical os. Can I travel by road or by plane by this time ? Is sex now allowed?
