Congratulations on your pregnancy! As you’ve said, ligament pain is very common in early pregnancy, as is trapped wind. There are two ligaments on either side of your body which go from the top of your uterus into your groin. They are there to support the uterus. These ligaments start to stretch in pregnancy, and this can sometimes lead to pain. This often happens especially if you do anything that puts any extra strain on them, like walking, lifting or bending, or even coughing or sneezing.
Trapped wind can also be very uncomfortable and it’s often linked with constipation and bloatedness – one of the pregnancy hormones relaxes the gut and slows it down. Eating and drinking as advised for combating constipation (water and fruit and veg) may help with it, as may regular gentle exercise.
However, if you experience any very sharp or continuous pain, bleeding or shoulder tip pain, do see your doctor straight away as although rare, it’s important to rule out an ectopic pregnancy http://www.nhs.uk/Conditions/Ectopic-pregnancy/Pages/Symptoms.aspx
