Pubic bone is killing me

How can i ease this pain? I have a hip support coming in the mail. What can i do for the pain in the mean time? It litterally feels like ive broken my vagina bone and its so painful to sit, walk or do anything in general!! Laying down on my back is not an option as my sciatica nerve pinches and causes more pain and that stays around for days!! My son is 14 months old and i cant even pick him up! I'm only 15 weeks along btw and this pregnancy is already giving me grief my next appointment isn't until mid next month.. this kid also sits down low in my vagina aswel which causes presure could this be the reason to my pelvic aches? Thankyou ladies
