You are Rhesus positive (O+)

Rhesus factor problems
When you''re pregnant, it''s important to know whether your blood is Rhesus positive (Rh+) or Rhesus negative (Rh-). This will be checked from the blood sample that you give at your first antenatal appointment. If you''re Rh-, it''s important to know whether your partner is Rh- too. If he isn''t, there''s the possibility that your baby will have a blood group which is incompatible with yours, and this can cause problems.

Why is the Rhesus factor important in pregnancy?
If the blood of anyone who''s Rh- comes into contact with Rh+ blood, it will react to it as ''foreign'' and will develop antibodies to the Rh+ cells that will kill them off. This works in much the same way as when your blood develops antibodies to the cells of viruses, like colds and flu, in order to destroy them. And as with antibodies to colds and flu, once the antibodies to Rh+ cells have developed in the blood of someone who is Rh-, they stay there.

If a Rh- woman has a Rh+ partner, it''s very likely that their baby will be Rh+. This means that if her blood comes into contact with her baby''s, she''ll develop antibodies to it. This is unlikely to happen during a first pregnancy, but can happen when the baby is being born, when some of its blood may get into her circulation. It can also happen if she has a miscarriage or a termination or, occasionally, after an amniocentesis or CVS test. If it does happen, the woman will produce antibodies to the Rh+ blood. They won''t affect her first baby at all, but they''ll stay in her blood and if she becomes pregnant again, problems can arise.

If a Rh- woman who has antibodies in her blood is pregnant with a Rh+ baby, it''s possible for her antibodies to pass through to the baby and damage or even destroy the baby''s red blood cells. This can lead to the baby becoming anaemic or developing jaundice, or occasionally to more serious complications.

What can be done about it?
Fortunately, Rhesus factor problems are almost entirely preventable. Women who are Rh- are routinely given an injection of a substance called Anti-D shortly after the baby is born (or after a miscarriage or termination). This destroys any Rh+ cells that may have got into the bloodstream so that they won''t produce any more antibodies. In some areas, Anti-D is given to Rh- women during pregnancy, but this is not routinely done everywhere.

At the first antenatal appointment a blood test if carried out and Rh- women are checked to see whether they have any antibodies. They may also be offered more frequent blood tests during pregnancy to make sure that they haven''t started to produce any.

If antibodies do show up, they may be at a low enough level not to cause any problems to the baby. If there''s reason to think that they could be affecting the baby, it may be necessary to run tests to see how severe the effects are. In the most serious cases, it may be possible to give the baby a blood transfusion before it''s born. In other cases, the baby may need to have its blood exchanged after the birth.

I''m 0+ and fall pregnant very easily, despite having polycystic ovaries and only one fallopian tube.
