What's wrong with me?

Pip • Pregnant with a little boy • c-section is booked for 4th July 2016 at 8am ✨
I've had two periods this month (4th-11th and 14th-17th) . So I don't know when I ovulated. I have thick white creamy discharge now, sore veiny boobs, sore nipples and have this acid like feeling in my throat which is making me nauseous and been sick twice at 10pm tonight. We're trying for a baby... Don't even have a clue when I'm due on my period..
