Help please 😣

I have done an early pregnancy test (10days post ovulation) because I have been feeling different, but I can’t really explain why. That test was negative, my period was late 1 day. But it seems like my period finished already after 2 days, which is unusual as my periods always last 5 days. I’m having really bad back pain and now I’m questioning myself if I actually had my period or not. I don’t know if I’m just being too anxious and paying too much attention to how I’m feeling. I’ve been through a lot of stress lately and feeling irritable. Should I repeat the pregnancy test? I don’t want to get my hopes high and then get disappointed once again
