Hi, I'm 19years old and I have been in a long term relationship and recently something weird happen me and my boyfriend acted irresponsible ,and had sex without protection several times now and between that period I wasn't using any pregnancy prevention so what I'm trying 2 figure out is why haven't I been falling pregnant don't want a child now but I'm worried that in future when I'm ready for children I might actually not be able to conceive.any ideas why this is happening?

Its all timing and luck. Seriously....timing and luck.

Next time you might find yourself pregnant. If you are worried, then why are you taking chances?

You let your boyfriend have unprotected sex with you and blame him? Yeah that's weird all right, but as Smoothy said it can happen anytime and because it has not yet doesn't mean it won't. I assume you have regular check ups, so ask your OB/GYN, or doctor about BIRTH CONTROL for you (in case more weird stuff happens), and make sure you are safe and healthy when you do want to get pregnant. That's the best way to address future and present concerns and most weird stuff.

This is normal for sexually active humans no matter what pregnancy prevention is used. Nothing is 100% except abstinence. Weird stuff(?) happens.

Sometimes a healthy couple can take up to 12 months or more, to get pregnant. It was just a matter of good luck at this point. Has nothing to do with ability to become pregnant.

You may be on a hot streak but keep rolling the dice without protection and you just might win a pregnancy. Just when you don't want it.
