Clexane works to reduce the ability of your blood to clot. One of the major causes of miscarriage is clotting problems, which is why it can help to use clexane for a pregnancy. Different protocols exist as to whether you start at confirmation of a pregnancy, ovulation, or the start of the cycle. You would need to ask your doctor for more information on that one.

Pessaries - they are simply used to help lift progesterone levels. Usual method would be to use them from ovulation and then continue once a pregnancy has been confirmed. Low progesterone levels are often found with pregnancies that miscarry, so sometimes increasing progesterone levels can help. Be aware that the discharge when using pessaries is fairly icky.

Have you been tested for autoimmune problems that may lead to miscarriage?
