Talk to Gynecologist on Pubic Symphysis Pregnancy

I’m 7 weeks pregnant and have started noticing pain in my pubic bone, i had this extreme pain in my first pregnancy too and it started off in 8th week, i couldn’t walk properly, change pants while standing, or even sit with cross legs, roll over in bed, everyday became very painful and even after delivery it took almost 10 months to completely heal. This is my 2nd pregnancy and now again I’m noticing the same thing. I was 60 kgs in my first pregnancy when this happened and this time I’m 70, height is 5’6. Is there anyway to prevent it or any treatment for pain? I used to do some exercises in my first time but none of that helped. Any belt that would help? And why exactly does this happen to me and not everyone ? Pls i need advice from an orthopaedic and gynaecologist both.
