help!!!!

so the last two nights my son has been talking about babies and saying im pregnant and turning upside down and im two weeks from when im supposed to have my period and i was lightly spotting two days ago and cramping in my lower pelvic area.. but my s.o. got told there was a very low to no chance of him being able to have kids cause hes got stomped on to much during rodeos and that if he got someone pregnant it would b a miracle.. what are your thoughts? is spotting and cramping early symotoms?
