hi, I m 25 years old. I have been having a few symptoms lately that i m a little worried about. First I started to get red circles on my stomach and back it took a full day but they went away, I have been having mild but annoying headaches every night when I get home from work, today my eye went blurry and when I stood up I though I was going to pass out (I do wear glasses maybe my prescription?), my stomach has been feeling off for a while now (I just got used to it being irritable), also I have been on birth control for a while and today for some reason I started to spot? I have been very stressed out could this all be due to stress? Thank you for your help.
