Does sex before your period make it come late?

Okay, I had protected sex, and he didn't even ejackulate. But We had sex, a day before my period was supossed to start.. & it didn't start? Does having sex the day before you start, throw it off a couple days or should I be worried?

Okay, so according to this article I found, your period is not considered late until 5 days after you were supposed to start and having sex would not be the cause of it (unless you were pregnant). But you had protected sex, so things should be okay and if you don't have a period within that time frame, you could always take a test... here is the website:

Good luck!

It's probably just hormones, I wouldn't worry about it until you are a week late, then I'd get a pregnancy test. Wish you the best and be safe.

don't worry...your period can be off by like 5 days and still b normal

plus..the whole sex thing has probably got you all paranoid so just relax ..everythings ok!

Actually, intercourse near the start of your period CAN throw off your cycle...

Throw it off how much?

not by much..maybe 2 or more days- its nothing you have to worry about unless you completely miss your period.

You should probaly see a docter.

I stared.

like a couple days ago,
& its ganna be a full period.

but thanks anyhow.

I just went through the exact same thing. Had PROTECTED sex the day before I was supposed to start. And then I was freaking out because I didn't start. But I ended up starting 5 days later. I think it was a combo of sex rights before menstruation, which I've read can make you late, plus me being paranoid and stressed about being pregnant.
