Discharge question!

Recently I've been having a LOT of discharge in my underwear, mostly very wet and stringy. Today, however, I was going to the bathroom and noticed a large amount of creamy, kind of sticky discharge and I've never had that before. I'm supposed to get my period next week, so I'm wondering if this is just normal ovulation CM, or something else. I've also had some symptoms of pregnancy like bloating, extreme constipation, sore nipples, increased appetite, etc.
