I'm 18 years old and I've had unprotected sex ever since I've started I've only been with one guy and I'm not pregnant. Which means I wonder why I didn't get pregnant? I believe I was fertile and he cummed in me at the moment he's cummed in me every time we've had sex, but I'm assuming its his infertility. I still have yet to wait for my period around this coming week and wait to see if this is going to be a sign. I'm not trying to get pregnant or anything condoms weren't around either, but I'm willing to have to baby for better or worse. help? is greatly appreciated.

Of course you could get pregnant. If you aren't trying to get pregnant, then not using birth control means you are trying. So, if you are "willing" to have a baby, sooner or later you will get pregnant. Do you have a job and are capable of raising a child at the age of 18? Is he ready to support a child? I hope you two have done some planning.

It all has to do with timing. Your ovulation period and just luck.

It has to do with how many times you have sex, when you have sex and more.

If you are having regular periods, most likely you are ovulating regularly. It's possible either or both of you have a fertility issue, but the lack of pregnancy does not automatically make it so, and only medical testing would tell you for certain.

As as was said, often it is simply timing... both when you are having sex and for how long you have been having sex. It is likely that you have just been lucky.

If you are not financially and emotionally ready to provide all that a child needs for years to come at this stage of your life, best not leave it to chance. There is so much that would change in your life if you were to get pregnant at 18, and it's not all things that you would like.

It can take many months to conceive even if there is no physical issue with either party.

You don't say how long you have been trying. But generally an OB/Gyn is not going to start fertility testing until at least 6 months of trying, usually longer.

As the others have noted, at 18 and unmarried (apparently since you referred to partner and not husband), it seems rather questionable that you are prepared to be parents. I hope we are wrong, but it would help us help you if gave us more background.
