If you’re usually regular but miss a period (not pg) what happened?

[DCITennison]

My period isn’t very late, I’m definitely not pregnant, and it’s really bothering me. I didn’t realise I’d feel like this, or how how much I rely on knowing where I am in my cycle.

I’ve been logging my periods for years and looking back over them I’ve had one 20 day and one 30 day cycle over the course of the last 5 years, other than those two periods it’s always between 23 and 27 days.

I’m now on day 40.

I’m 40 so I suppose could be the start of things getting a bit unpredictable. But I hate it!

I can deal far better with feeling down or anxious if I know it’s because I’m in the week leading up to my period. Looking and feeling bloated and puffy is bearable when I know it’ll sort itself out in x amount of days.

Not knowing where I am now has really thrown me for a loop.

So, moaning out of the way, if you’ve been in this position what happened? Did you just miss a period and then come on roughly when the next period would have been due? Was it the start of your cycle being all over the place?a one off?

My period is very late.
Doh!

Lack of exercise sometimes makes my period late. Normally I’m a regular gym goer but if I slack, my period comes late
Sometimes there’s no explanation!

This has been happening to me since September. All regular then no period at all in September then I've had one every 2-3 weeks since.
Saw GP, had lots of blood tests and now I'm waiting on a referral to check for PCOS.
My GP did say it's normal to skip a month. If you don't have one when your next cycle would be due I would book an appointment

Major variation in diet or exercise. Perimenopause.

The first time I ever missed a period was during my A-levels. Totally absent, and I don't think I even had any PMS. The next one came exactly as expected and was a completely normal period. So, a two-month cycle.

Since then, the only times that I missed a period were times of great stress (appart from pregnancy/breastfeeding/contraception/peri-menopause). But that first time was IIRC the only time I ever just skipped a period, with no ill-effects. Every other time the skipped period came 2-3 weeks late, and came with a vengeance. Often heavier than usual, plus felt like a double dose of PMS because the PMS lasted longer.

Late periods had no other effect on me.

At 40, it could be the start of peri-menopause.

Stress! I once went 3 months without one and thought I was in peri menopause, it arrived once I stopped thinking about it and have been pretty regular since. (I'm 42)

Stress

I started experiencing the same thing 1st your age after a lifetime of 100% regular periods. It was the start of peri-menopause for me, and I would bet it is for you, too. It was the first symptom I had, and others soon followed. Are you having any other issues?

This is all interesting.
This last month could definitely be described as stressful, some very sad news about my mum, although I thought I was dealing with it reasonably well.
I’ve also been exercising more these last few weeks.
I’m not having any other issues really, but I do feel quite lethargic and down. If I ever feel this way I’m usually able to pin it on being pre-menstrual, and helps to be able to explain it in that way.
I have no sense that my period is imminent though, no sore boobs, and I always get boob ache in the run up.

I’m pretty sure I read somewhere that the doctor is only going to act if you’ve missed three

Happened to me this year. Usually I have really short cycles, around 23-24 days. I somehow managed a 45 day cycle and thought it was the start of perimenopause. Back to normal since then, though. Really odd.
