So sore .. what is it ?

Hi ..... this a bit TMI but I’m too embarrassed to show my doctor. Think I’m going to have to. Basically I’m 34 weeks pregnant with my daughter , have a son who is 3. For the past 6/7 weeks iv had pain and discomfort which is now getting worse and worse... it started like a bruised feeling on my Pubic bone (left side mainly) when I stood up... hard to walk etc pain in groins also feeling stiff sore and weak. Was told this is pelvic gurdle pain. today I looked in a mirror... at that level 😮 my pubic bone is actually swollen it’s like tripled in size ! It feels like fluid is also underneath my pubic bone ...! It’s so fat looking! Is this normal ???? I’m very sore when walking and again left side is worse.... I will end up on crutches at this rate ... today got so bad I couldn’t lift my leg to get into the car without wincing in pain
