Pubic bone pain I need advise please

7 weeks PP and I wake up multiple times a night with a throbbing pain In my pubic bone. It feels like someone hit me in the vagina with a bat. I have to get up and walk around for it to fade off. It happens after I've been asleep for a few hours. I went in for my check up and I was told it's probably bruised. But it just started hurting 5 weeks PP so why would the bruising be delayed? She told me it's not symphysis pubis disfunction but I think it is. Has anyone else experienced this? If so what was the cause and how long did it last?
