Doggy style hurts me badly

I've tried many different positions and I always have very sharp pain when doing it doggy style. It feels as if the dick is thrusting on my cervix. One time it was too painful that I had lasting pains for several days after sex. I had sex with guys of varying size and it hurt regardless of the size of the D. Should I be concerned? Or does this just mean that my cervix is located bit more lower than average? Have anyone had this problem and had it solved? Thanxx😚
