Hello doctor. I have had unprotected sex with my wife immediately she ended her periods, ie the next very day. Her period ended on last Wednesday morning and we had on Wednesday night and Thursday and friday. What are her chances of getting pregnant. We have not planned a child now but she didn't take any contraceptives. Hence what we can do now? Now it is almost a week. She is afraid that she will conceive. P. S:- She has only 3 days periods generally. Sometimes the fourth morning it goes.
