New To Sex

I tried to have protected sex for the first time with my partner one week ago. He did not ejaculate during the process nor did he go all the way inside due to pain. I am not on birth control and a condom with spermicide was used. All throughout the week, I have noticed a large amount of white and clear discharge from my vagina. I'm not sure if pregnancy or STDs are an explanation for the discharge and if I should be worried. Any help would be greatly appreciated!
