Pregnancy perhaps

Do not tell me to test, I know to test. I just want to know how likely this is. Okay so I had sex unprotected multiple times for the 4 days following my period. That was may 27th-31st. On the 7th I had light pink spotting for a few hours. I was supposed to ovulate yesterday I believe. I've been having odd symptoms and am curious if that spotting could be implantation even though it was only a week and a half after my period and about 2 weeks before I was supposed to ovulate.
