Does exercise change your period?

Question

I used to workout regularly and my periods used to come on the same day every month. Now that I'm not so active my periods have been completely random and unpredictable. Does working out effect your period. Does not having a regular workout routine make me have an irregular period or should I be worried about it?

Answer

Yes it most definitely does. I've heard of some women who run a ton of marathons that don't get their period every month because of it. Mine wasn't ever affected (always random and changing as normal) but for my sister it makes hers lighter. It all depends on you, I wouldn't worry about it though.

Answer

Yes! If I start a new routine or change the intensity I usually skip that month.

Answer

I lost my periods for months when I was running extensively. When I stopped the first few months when it returned were hay wire. But it evened out

Answer

It makes mine lighter and shorter and helps with cramps as long as I work out at least 3 times a week for an hour

Answer

When I ran cross country it would always change my schedule. I wouldn't worry about it personally because I have heard from plenty of others that exercise changes their cycles for them as well
