A few weeks ago my wife got a positive pregnancy test. She had missed her period by a couple weeks and we thought she was pregnant. The test came back positive. However, last week she had her period. We thought that maybe it was a miscarriage or something, but after the period ended she continued to have morning sickness and other signs of pregnancy. We are currently traveling and so have been unable to get to a doctor. Is this something that we should get checked up for? Where we are (Norway), they do not do ultrasounds until 18 weeks along and it can take weeks to get an appointment. Is this normal?
