Answer
If your last period started on March 21, you are now 8 weeks pregnant. The best times to take a sonogram is at 12 weeks and at 20 weeks gestation. The diarrhea may have some bile salts in it but it is nothing to be alarmed about. If you have diarrhea you should make sure you drink a lot to prevent dehydration.I would wait to have the first sonogram until June 12.
