On 5th June me and my wife had unprotected intercourse, just when I felt I am about to ejaculate I pulled out penis and saw a drop of sperm coming out. I am not sure if one drop came out inside vagina or not.
21st June is her period date, we checked on 21st with prega news , it tested negative, we again checked on 23rd June, it was negative, and we checked on 27th June again, it is negative, but period is still not there.
Is there still chance she can get
pregnant?
What are the measures ?
