Hi!
If you were my patient, I would write you a prescription for Plan B. (Which is emergency contraception.) As it is popularly known--the "pre-***" or seminal fluid which occurs prior to the actual ejaculation contains sperm, and all it takes is one of those little guys to make a whole baby!
Check out my blog article on PlanB (this site)
Good luck!
Dr B
