Had light bleeding twice during 10th-12th week due to low lying placenta reaching cervix. Was advised bed rest with weekly dosage of proluton depot 500mg inj along with other medicines. Have been on rest for 7 weeks since then. Now at 20 weeks anamoly scan, placenta is still low 1.5 cm from internal os. Medication is being continued. I am also facing  round ligament pain (pelvic and inner thigh muscles) at the time of getting up from a position. I wanted to know if it is safe to travel for office by cab. Distance 12-15km one way.
