how much it will affect your unborn baby in the first 6 months of
pregnancy.

delay the onset of labour and prolong its duration.
They may also increase the likelihood of bleeding in the mother and in
the baby.
If you need to take these tablets, your doctor can help you decide
whether or not to take them during the first 6 months of pregnancy.
Breast-feeding
Mefenamic acid passes into breast milk and can affect the baby. You
