Antenatal testing and monitoring is attentive here, both in the private and public system. Tests carried out as a matter of course (such as for streptococcus) would have to be specially requested on, say, the British NHS. As soon as you know you are pregnant you should have a general check-up with your GP. He or she will assign you a gynaecologist, usually based at the hospital where you will give birth, though you can opt to see your usual gynaecologist if you already have one. You will also be assigned a midwife (comadrona), and be set dates for tests and scans (ecograficos). There are usually three scans, corresponding with each trimester. In the case of a routine pregnancy, check-ups (controles) with gynaecologists are usually monthly until week 36, then fortnightly to week 41, and then weekly or more until delivery. More regular check-ups would be likely for older women, or those deemed to be at risk from complications. Blood tests for Downs Syndrome are always recommended. Women over 38 are offered amniocentesis, though these can also be requested by younger women with other risk factors. This timetable is roughly the same whether you attend a private clinic or use the public system. In the public system there will be ten or so ante-natal classes for first-time mothers, usually coordinated by the midwife assigned to you. Women in private care are likely to have access to additional services, such as swimming therapy and relaxation classes.
