Could just be everything in your belly getting pushed upwards to make room for your baby. Make sure you're hydrated and breathing good too because those things I notice can cause pain below your ribs
I drink a lot of water and breathe normally it just hurts to breathe when I get the pains. Ive had them a total of 4 times and its always in the morning. I just don't know what causes it.
Could just be trapped gas from everything finding new positions. Lay on ur left side for a while when that starts to happen.
I had that..pain only got worse until my baby dropped. Now my pain is gone and i'm so happy. Started getting rib pain at 20weeks and my baby dropped at 33weeks. I'll be 38 weeks on Tuesday.
