Clomid and TTCing for the first time.

Alex • Expecting our first baby on December 1, 2016 and loving every moment of pregnancy and the final months of just us <3
Hello all,
I am wondering if anyone has taken Clomid, days 5-9, and had experienced any side effects? 
I am on CD 11 and I'm still having nausea and hot flashes, will this keep up during the entire month? Also, how soon did Clomid help women ovulate? 
This isn't first month taking it and I'm wondering if tracking my BBT is the best way to see if I ovulate.
