It takes the average healthy couple a year to get pregnant, so don't panic if it doesn't happen immediately. Here's some answers to your questions.

1. She needs to learn her cycle to know when she ovulates. Have sex around her most fertile time to increase your chances of conceiving.

2. Different holes? You need to have sex with her vagina to get her pregnant.

3. Time of day does not matter. Just have sex when she's fertile.

4. There's no time to NOT have sex.

5. Not really. They say that if you have sex a few days before ovulation, you increase your chances of having a girl because girl sperm last longer (but swim slower) than boy sperm. But really, you have a 50/50 chance anyway.

6. Have sex. It's that simple.

Moreover, she had her periods on last sunday and today we had sex . Its nearly the fourth day after her periods. Is there any 99% possibility of her to become pregnant ?

I don't think you guys need a forum - I think you need a biology lesson.

Your wife needs to keeo track of how many days are between her periods (usually around 28 days but this can vary from woman to woman and from month to month. a woman will ovulate (release an egg which is to be fertalised ot make a baby) around 14 days BEFORE her period. So find out when her period is expected and count BACK 14 days from there and have sex a few days BEFORE this as it takes time for the sperm to travel to the egg.

A VERY BASIC RULE OF THUMB IS:
1st day of period is CD (cycle day)1
2nd day of period is CD2 and so on...... in a 28 day cycle you need to have sex from CD 10 through to CD16 to catch her fertile days. This is a very basic rule of thumb and it is much more complicated than that but I think try that 1st. I think you both need to do some proper research - use google to look up 'fertility' and 'ovultation'.

I know this is an old thread, but if you don't want to have to deal with cycle days and you want to keep it simple, then make sure to have sex every other day- that way you'll be sure to hit AT LEAST one of her most fertile days.
