Nausea??

Emily • Our rainbow 🌈 baby has arrived! April 3, 2017.
So I got a vvvfl the day before AF last month (June 24). My flow was very light but I had a CP in May so I expected a weird cycle. 
I got another vvfl last Friday on the Frer curved. I bought two other brands and got negatives so I figured it was an indent. 
Today however I have some nausea, much like when I was pregnant before my mc. Should I bother to test again? What are the chances?
