11 dpo + a few symptoms.

So I am not quite sure what my body is up to and I've searched for answers all over the internet. I ovulated on the 26th give or take. On July 4th I went to the bathroom and noticed a little bit of pink spotting when I wiped. Thought AF was early. Went backwater and the spotting was gone after an hour. 
​The past two days I've had headaches and have been a little queesy. Also having a bit of an upset stomach.  Period is due on the 10th. Hating the anticipation but trying not to get my hopes up. What do you think possibility I could be pregnant?
