Ladies should I go into the ER?

This is my fist pregnancy I’m 7w3d. Last night I had such a bad fight with my husband I screamed and cried for hours. I was so stressed out like never before in my life. Today I woke up with a sharp constant pain on the right side of my pelvic. No blood tough. But it feels like there’s something coming out of my vagina I wipe and it’s clear some sort of discharge. What do I do ladies I’m home alone. I don’t want to go to the ER if it’s nothing serious, people with real emergencies need them but what if it is? I’m lost and crying and in pain what do I do. I haven’t been to the OBGYN yet so pregnancy hasn’t been confirmed by blood exam only at home pregnancy test. Period is late by almost a month. I’ve been having all of the pregnancy symptoms. Supposed to go to the doctor for blood exam tomorrow but woke up with this pain. Help me please
