Could there be a chance I'm pregnant?

So according to Glow I ovulated about 9 days ago. And my husband and I did have intercourse that day, days before and days after. Yesterday and today I had very light pink discharge and today I started having some nausea throughout the day. Aunt flow isn't supposed to arrive for 10 days. (I have long cycles) I have a very heavy flow every period and its still awhile away for it to be my period. I had never ever had any kind of discharge like this so it really makes me wonder. My husband and I have been TTC for 9 months now and it would be our first.
