<\/span><\/h2>\nEven though your ability to conceive will not be affected by having a heart shaped uterus<\/strong>, it does bring some dangers to a successful pregnancy, with a raised chance of miscarriage. Researchers believe that this is because there is a reduced capacity inside the womb and also that the unusual shape may lead to irregular uterine contractions.<\/p>\nWhat is the risk of miscarriage?<\/strong><\/p>\nUnfortunately, it is difficult to know the extent of the risk of miscarriage in each individual case. A study conducted by the UK\u2019s Royal College of Obstetricians & Gynaecologists estimates the risk to be anywhere between 1.8% and 37.6%. This wide range is because the only available studies so far have included women with one, two or three miscarriages and they do not differentiate statistically between first-trimester miscarriages and second-trimester miscarriages. The study does note, however, that second-trimester miscarriage appears to be more common in women with uterine malformation, but that this may also be a result of the cervical weakness which is often also present.<\/p>\n
Cervical insufficiency<\/strong><\/p>\nThe weakness of the cervix which is often seen in women with a heart shaped uterus<\/strong> is known as cervical insufficiency. Normally the cervix, the lower part of the uterus which opens into the vagina, is closed and firm during pregnancy, and only starts to soften and open as you prepare to give birth. If you have cervical insufficiency, it may start to open too soon, leading to a miscarriage or premature birth.<\/p>\nIncreased likelihood of Caesarean Section <\/strong><\/p>\nA heart shaped uterus <\/strong>also brings an increased chance that the baby will settle into a breech position, which means that the baby\u2019s bottom or feet, instead of the head, are facing downwards towards the cervix before birth. In this case, doctors monitoring your pregnancy may be more likely to recommend a Caesarean Section.<\/p>\n
