what are the chances??

spent the weekend with my boyfriend, hes in the air force so i only see him weekends since base is an hour away, we had sex all weekend, friday night, he came in me saturday morning like 2 times, then we went and got the plan B pill, we went drinking saturday night, sunday night i stood with him and he came like 3 or 4 more times inside me that night, and i barely took the pill this morning (4-9-18), after the 1st day of him cuming in me i had like a clear discharge, could that mean anything? what are my chances of pregnancy?
