weird pelvis pain

does anyone ever get weird pain like stabbing/ cramping on one side because i keep getting it on the right side and idk why it’s like that it just started happening out of no where. i looked up and it said it can be pregnancy symptoms but the last time i had a chance of that happening was 3/31/18 but that was just there being a chance that my boyfriend had cum on his fingers and fingered me and i’m supposed to get my period 4/19/18
