How soon will you get the sign and symptoms of pregnancy?. Will constipation starts on the first week of pregnancy? And will the Dr. do an internal U/S during pregnancy?.
Hi Priscilla, welcome to Chat Doctor. Earliest you can suspect of pregnancy is when you miss your regular period. Earliest way to detect pregnancy is by serum B Chat Doctor test. One week later it becomes detectable by urine pregnancy test. These tests detect pregnancy much before you start having symptoms of pregnancy. Constipation is not a sign of pregnancy. Internal ultrasound is done in the first three months of pregnancy, after that generally it is done transabdominally. Wishing you all the best and hope you are pregnant.
