Off topic for this app, but possibly pregnant?

Okay, so according to this app I had a 22% chance of getting pregant this last Tuesday, and a 8% chance that next day.. My boyfriend did bust in me from that Tuesday to that following Friday. Not sure if 22% means probably not, or I could be anyways. I don't usually follow up on period trackers and such. I do have one year and five month old daughter currently. My periods have been regular. I could tell I was ovulating. I had discharge and cramps on Tuesday and the day before Tuesday. My boobs slighlty hurt the past three days and I have some cramps still going on. Not sure if the cramping is from sex because Tuesday was the first time I had sex in months.

Basically I am asking if regardless the percentage of getting pregnant means anything or not..
