So confused

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 May. I've had very sore/veiny boobs, yesterday I had thick creamy discharge, today basically nothing. Could I be ovulating or pregnant? I'm trying for a baby but it's taking forever! Don't get why I had two periods? But if I was ovulating surely I would have stretchy discharge. 
PLEASE COMMENT 😊 THANK YOU!
