RESPOND FAST PLEASE!

Should I go to the hospital? Im 39w 1d I'm super dizzy and am having a hard time focusing with my eyes. I've been super tired lately and extremely achy. It hurts to move and walk. I have a lot of pressure in my lower back right above my butt. My SO isn't home and I'm unsure what to do. I don't want to go to the hospital if this is nothing. But I've never been dizzy and have had a hard time focusing before. I just don't know if this is extreme enough? Thanks in advance!
