Ok this is my second pregnancy, exactly 2weeks remaining til due date. I have always suffered from mild-moderate stitch when walking from about 5months+ (with both pregnancies) but they generally fade off after 5-10mins of walking. I just walked a short 10/15min walk to the shops with my lil'un and had to continuously stop as the stitch was so severe and only down left side of bump. Is this just because of how late in pregnancy or should i be concerned?
