Anyone ever have symptoms before missed period? TTC #1

So it's been 6 days since ovulation. A few days ago I started feeling gassy and bloated. Even after having an 8 hour nights sleep I took a four hour nap today, cooked dinner. Now I want to go back to sleep. I couldn't even eat 3 bites of my dinner(chicken,rice,and corn) before I started feeling nauseous again and wicked heartburn. I've also had a major increase in bathroom frequencies.... Anyone else have that happen? What was the outcome?
