I have a sex at 23 rd of novber with my girlfriend without protection .
I know that I had not ejaculated sperm as the sperm always ejaculate at last but if it was ejaculated in between then can she get
pregnant . and she will have periods after 28th of November . we have two times but when the sperm spread out I clean it but no clear that properly .
So can she got pregnant if yes then sir please give tips to prevent fr.om pregnancy.
