Hey im 15 and have been on my period since I was about 10 then my first time was when I was 13 well my period has always been irregular but sometimes if you have sex too hard it moves your period or even when you firsu start having sex your period might be irregulas but you have to think is your period always light or is it usually heavy???Because in some cases you'll have one period when you first get pregnant and it'll be really light but you have to think for yourself what your regular flow is

Hi there, i'm sure you are a little worried right now, so I have some sound information for you. For the first year of your period, you can expect things to be very normal and then--bam!--abnormal. For myself, I could never predict when I was going to get my period. Sometimes I would go months before getting it again. The heaviness of flow may vary too. So what you're experiencing may just be completely normal for your body. You also had protected sex, which decreases the likelihood that you are pregnant...But did you have protected sex the whole time? Because men can pre-cum. Do you have other signs of pregnancy (you can look these up on the internet)? If you do, and this is a huge concern, take a pregnancy test. It will take no time at all, and could place your mind at ease. (and as an aside, because you are younger with limited capabilities to take care of a child, you should consider an additional form of birth control---but never forget to use a condom--you may trust your partner, but you can never trust who he's been with...)
