Hello Veronica.
There are many reasons your regular cycle may be disrupted, including stress and travel (which you've noted), as well as hormonal changes due to diet and exercise, change of birth control method, and more serious causes such as fibroids, endometriosis, etc.
I'd wait another week to see if the flow stops, and if it doesn't, then schedule a visit with your gynecologist to determine the cause. Dr. J
These are all potential symptoms of something amiss, so don't ignore them if they're recurring.
It stopped after 2 days flow, not heavy in both days... i think if it comes back again... i'll definately seeing a gyne.
at the moment, i try to rest more.
i also felt that i put on weight lately, tired and a little pain at my lower abdorment... i hope i'm not serious.
thanks so much for your reply, it helps..
