I feel feverish, rare headache/back pain, very rare cramps and today evening i found a small red mucus like ovulation egg... does it indicate that my period going to start? I'm over 7weeks now.. no other symp..

You should take a test, especially if you are over 2 weeks late. If you have had sex, you could be pregnant.

I'd agree with h_leann but the feverish part worries me. While it might be nothing, I can't recall fever being a common sign of pregnancy or period. I'd take a test AND call your dr for a check up.
