Could I be so lucky?

This might be long but I'll try and keep it short. Feel free to ask questions. I had a D&C may 13th for MMC. I had a negative pregnancy test a week later. 
Stopped bleeding/spotting may 28th. 
On 6th 9th and 10th of June I had spotting  brown in colour, it only happened one time on each of these days. 
Now it's been over 2 weeks I have had what feel like period cramps for the past week but just cm. My ovulation tests from the 12th June always come up with a faint line I have never got a positive ovulation test. Could I be pregnant? I have symptoms which I only usually get when pregnant like oily skin. Any ideas? X
