Feels like I’m ripping apart from the inside

I’m 25+2, and for the past few days it feels like my muscles are tearing about 2-3 inches above my bellybutton and around the same distance from my sternum. It’s very hard to the touch, and I’ve been moisturizing the outside but nothings helped.

Is this normal? I know baby is growing a lot right now, but this is absolutely horrible and it’s preventing me from getting comfortable or even being on my feet at my job. It almost feels like I’m bruised on the inside, I have an anterior placenta I’m not sure if that changes things or makes this worse.

I’ve heard of pelvic girdle pain as well as round ligament pain but I’m not sure what either are as this is my first time being pregnant. Is there anything I can do to make this easier or will it go away on its own? I would prefer to not feel like this for almost 4 more months.
