Ligament pain?

I’ve experienced bad ligament pain before with my first baby, but this time it feels like I can’t even perform normal daily tasks. Is this common? Do others feel this way around 4 months? It is a sharp constant pain the makes it difficult to take deep breaths and it is just not easing! I actually started crying just rocking my daughter to sleep because of how severe the pain was. I would love to hear from you ladies on how similar this was to your ligament pain, because it seems a bit extreme to me
