So my period is two weeks late and I am wondering

[TheFirstLady]

if I would be silly to do a pg test as DH has had the snip? They don't really reverse themselves do they?

Probably just one of those unexplained things isn't it?

Probably nowt.

Almost certainly nowt.

Oh it's nothing I'm sure.

Eek. What age are you if you don't mind me asking? Are your periods regular? Are you well? No illnesses recently? Anything big happening atm?

Am 45, but periods have always been totally regular up to now. No illnesses or upsets.
Could it be the menopause? I have no other signs that I know of.

Hmmmmm.

It could be the start of being perimenopausal. It's slightly unusual to go from very regular periods to one that is 2 weeks late. If you didn't ovulate (happens to everybody but more common as you get older), then that could account for it. Do you know if you ovulated?

When was the vasectomy? What were his sperm counts afterwards? Did they get down to zero?

I think it's between 0.5 and 1% failure rate for a vasectomy but most likely in the months following the procedure.

I don't know if I ovulated. I don't always notice (possibly I don't always ovulate).
Oh blimey, I never asked DH about sperm counts. The vasectomy was five or six years ago though and he had the all clear a few months later, so it must be OK, mustn't it.
Tell me to stop being paranoid and ON NO ACCOUNT to Google "failed vasectomy".

It's probably fine. I agree. Just wait a while and if no period by next week go to you gp.

Vasectomies that are going to fail generally do so in the weeks following the op. After that it's highly, highly unlikely. Even google would agree. And if it doesn't that's because people talking about failed vasectomies are the tiny majority that have experienced them, the millions who have had successful vasectomies tend not to worry about sperm counts and pregnancy tests ever again.

Try not to worry.

OK, so I Googled. Apparently the failure rate is anywhere from .05% to 1%. How unlucky would you have to be to be that one in a hundred? Or one in two thousand?
