Pubic (bone) pain

Ugh! I don't know what to do! I'm going crazy! This pain is so annoying and painful! With my first pregnancy I didn't develop this pain till I was later in my second trimester. But now 16 weeks with twins I've been having this pain for a while now! Ob says to just take Tylenol. But it doesn't help! My first pregnancy my dr prescribed me Tylenol with codeine and I never took them thinking maybe it was going to be too strong. But now I'm considering taking something stronger then just Tylenol. Any help or advice anyone?
Pillow between my legs doesn't help either
Nor have I been able to find a support belt that fits
