Me and my boyfriend decided to have sex, but he only went in about 2-3 cm and he pulled out after 1 minute. He didn't ejaculate or anything. I got my period 3-4 days later. I am really worried that I might be pregnant. There was no protection. Am I pregnant?

I seriously doubt it.

Any time you have sex you take a chance and I don't think it matters how far it goes in but if he didn't then proabbly not

Any time you have sex you run the risk of getting pregnant. Even though he may not have ejaculated inside of you, men have pre-ejaculate during sex and they cannot feel it come out. Pre-ejaculate does contain sperm.

When you have sex, no matter how far you go, you need to protect yourself.

Often times, we think that we can find ways of having sex, yet still get around getting pregnant. "If you only go in a little ways" " " if you pull out before you ejaculate" the list goes on and on. The short and simple truth, no matter what you do, anytime you have sex (protected or not) you run the risk of getting pregnant. Some things you do(like using protection)lower the risk, however there is still that possibility. If you don't want to get pregnant, be smart about the situation, and use protection. (two forms of protection is the smartest. Ex. Condoms and the pill)
