Positive opks for 11 days straight?

I've heard positive opks could mean you're pregnant, but af isn't due till the 12th so can't test. But I've been sneezing a lot with a runny nose, lower abdominal cramping, gained three pounds, veiny breasts and stomach, tons of white creamy discharge, super sleepy but when I sleep I feel exhausted.. Could I be pregnant?? ✨💕💫💖
