i started getting similar at 28 weeks and hve been getting it on and off ever since. it just comes and goes, seems to be worse when i do more physical activity during the day (so if i walk a lot or lots of stretching doing stuff) - i got my Ob to chek it about 10 days ago and he made sure it was nothing via scan and palpating - it seems i "might" have a small hernia near my belly button, but nothing certain. Gremlin seems to think it's the PERFECT place to push on my tummy though, so it can be extremely uncomfy sometimes

if it is worrying you, contact your care provider - and even if it dissipates completley now, mention it to your care provider at next appointment just to make sure they're aware of it
