Can your period cycle change?

Is it normal for your period cycle to change after..?

• So back in January I lost my virginity, and we were safe. I than got my period 2 days later and it continued into February(my period). But then i never got it again for the rest of the month, my cylce was 28 days long, and has been since i was 12 and first got my period. I'm not 17. My period than came again in March. 42 days after my period in January/February ! Is it normal to change so drastically after having sex? I got so worried in February because i thought i was late and did a pregnancy test even though we were safe and it was negative. (We use a condom and he pulls out with a condom on) we decided to stop having sex now though because we're still to young. And have stopped since February! So could my cycle have changed from 28 days to 42..? Thanks

• Answer:

  It is possible. My cycle changed after losing my virginity and it took a couple months to get back on a normal routine. Don't stress about it. If you get too concerned take a pregnancy test to put your mind at ease. :)
