Is my period coming in having a pregnancy scare

On March 19 I gave my boyfriend a hand job he did not cum or pre cum. But minutes later I touched myself. I'm just paranoid that a freak accident took place when my boyfriend is 101% sure nothing happened. I ovulated on March 28. My period comes in exactly a week. My cervix is low hard & kinda opened. Only symptoms I have are sore boobs on the sides only when I touch them & just moodiness. I don't feel pregnant but I am scared
