How to get My girlfreind pregnant fast we been doing it for a long time with no condoms and nothing heppens

Something wrong with getting married first, so that the child has a stable home?

See your doctors.

Have full tests run to make sure you are both fertile and that nothing is wrong.

If necessary, visit a fertility specialist.

Track her ovulation and have sex on the day she ovulates and the days immediately after.

Break up, then get drunk together and use a condom... seemed to work for a few of my friends :p

Well we seem to be skipping the marriage step but OK

Most recommend the cheap way is have intercourse every other day and if that doesn't work in six months to a year then you need to go see a doctor

How long is a long time ?

How old are both of you?
