I have been diagnosed with Placenta Previa Grade B during my scheduled NT scan. currently I am at 15weeks gestation. my doctor has asked me to avoid stressful work for 2 months, however, he said bedrest is not necessary since I don't have bleeding. Of late, I have this sharp pain(not severe) in the lower right side of abdomen ( right at the place where  the sonography wand is placed during the USGs)..pain comes when I am bending even half or bit or walking at normal pace (inside room) or doing any normal activity and not idle...the place is a big tender now.. is this pain normal  or  should I be concerned because of placenta previa? no bleeding as such...
