Brown spotting no period. Could I be pregnant?

[Honeyx1]

I’m 10months PP, however my periods have been like clockwork since 3m PP. I was due on yesterday but have had no symptoms and only brown discharge which I never get, I usually have heavy bright red blood straight away.

this morning I have only brown spotting again, slight cramping but nothing more.

i did a test yesterday and today both using second wee and no line.

should I keep testing or just accept that my period is late and unexplained?

there are twins in my partners family which I have read can cause false negatives?

Twins can only run down the female line not the male. So unfortunately it makes zero difference to the chances of twins if there are twins on the male side of the family.

The reason they say twins can cause false negatives is occasionally HCG can be higher in twins. But this only happens when HCG is VERY high and causes something called the hook effect. It cannot happen in very early pregnancy as whether it’s a twin or single pregnancy the HCG will not have risen that much yet. Google says HCG needs to be over 500000 to cause the hook effect. At around 4 weeks pregnant most people’s HCG, even with twins is under 2000. If you really wanted to test the theory though the way round it is to dilute your urine with water so the HCG isn’t as high and then test. But I would say it’s extremely unlikely to be related to the hook effect if you would only be like 4 weeks pregnant.

It doesn’t mean you’re definitely not pregnant. It just means you might still be to early to test positive. Unless you know exactly when you ovulated it could just be you ovulated a few days later which will mean your period is a few days later.
