Brown spotting after ovulation( no pic)

I posted this and got no answers before.... Anyways I'm irregular and finally got a semi positive opk like a week or 2 ago. I begin having cramps on and off for 2 days. A few days after that I begin to have brown spotting. I thought af was about to start but by the end of the day I was still brown spotting. It happen for 2 days now nothing. I have been semi nauseous but the that's the norm for me since I have a funky stomache. I'm waiting until July to test but my question is do you guys think its possible I'm pregnant?
