Hi, I'm 24 weeks pregnant and so far my pregnancy has been very straight forward. This is my second pregnancy and my last one was fine too. I'm not an overly fit person who goes to gym etc but since moving to Sydney a couple of months ago I've been doing a lot more walking than I used to. On average days I will walk about 5km, on a weekend can be up to 10km pushing a toddler in pushchair. Whilst I presume it's good to keep active during pregnancy I have noticed on days when I'm walking a lot I often get pain around the sides and underneath my bump. I have no bleeding, baby is active etc so I believe it's just muscular pain from weight of bump but was just wondering whether it's my body's way of telling me I should be taking it easy or whether it's just a sign I'm using my stomach muscles more. Any thoughts?
