flu very nauseous, no other symptoms

It's always possible that being very sick can stop your period. But only with real flu—people often confuse flu with flu-like symptoms. Flu comes on suddenly, you can get up to 40°C fever, everything in your body hurts—skin, hair, muscles, really everything. Real flu often lasts up to 10 days. Flu-like symptoms mean feeling achy, having a cold, headache that can be linked to the cold, sore throat, etc. So it's quite possible that you succeeded, but if you really have the flu, it could also be due to that. I hope the difference between the two is clear now.

I’ve had flu-like symptoms during my third pregnancy now. I didn’t even know I was pregnant... we weren’t trying anyway ;-)
One evening, sitting on the couch... sweaty... feeling feverish, my neck and head hurt, etc. But it felt really weird because I was hungry and still running around the house... and eating. Normally, when I really have the flu, I can’t get up or down.
The next day it came back, and again in the evening, same thing, like this for two evenings, and then it went away...
I did have some brown discharge with flashes, which turned out to be implantation bleeding afterwards...
So who knows, girl! It’s always tricky to tell these things apart... whether it’s really the flu coming on or if it’s just symptoms of a possible pregnancy!
Just wait and see, and if not, I’ll really throw a test at it..

Just had the same thing.. I've had brown discharge once a day for the past 3 days and nothing else..
I've had a cold and am exhausted since yesterday..
I'm on day 30 of my 32-day cycle today.
Should I test tomorrow?

I'd do it, leave your doubts behind, good luck!
