Newlywed pains

Hey ladies! My husband and I just got married almost two months ago and we saved sex until marriage (we were both virgins). Ever since we started having sex I have pain during it. I know it is supposed to hurt at first but I just don't know how long it'll take me to get used to it or if there is anything I/we should be doing differently to help it be less painful for me! 
Thanks for any advice!!
