The pull out method isnt always reliable as you can get sperm in pre ***.
So there isnt as much sperm so the chances of pregnancy are not as great, and it depends on the time of her cycle, but theres always a chance.
Use condoms or another form of b/c, or if she misses a period get a test.
hi
me and my boyfriend used the withdrawal system for almost a year without me getting pregnant but eventually we got carried away and he came in me.So its better to use protection.
