Can having sex 5 days before my period cause it to be thrown off?!

Having sex doesn't delay periods but getting pregnant does...

It really depends on how regular you are. If you are consistently regular and this is odd for your period to be off, I would suggest getting a pregnancy test. If it is negative, wait a week and take another one because the HCG levels could still be low if you are only a day or two late and can give a false negative. Look up pregnancy symptoms and see if you have those as well.

With my second daughter, I was able to find out the day I was supposed to start my period (but I already knew I was pregnant because of my body's cues and similarities to the first time, so this probably isn't your case). Most of the time it takes at least a few days after your missed period for the levels to be high enough.

If you are not, I would strongly consider birth control if you do not want to get pregnant.

Yes, unprotected sex can cause pregnancy. Even if he said he didn't finish. Even before a man ejaculates, alittle sperm can seep out.You should get a pregnancy test and if it comes out negative you should really consider going on birth control.

He doesn't need to finish inside of you, you can still get pregnant from pre-*** which leaks out when he is aroused or stimulated. You should go get a pregnancy test.

Not unless you got pregnant. I wouldn't worry until a week to ten days after your period should have started, depending upon how regular you are.
