Had my last period on 7th Dec, had unprotected sex with my husband on 14th Dec, then travelled from India to Canada I mean long flight on 25th, yesterday night when I went for pee and wiped, noticed a dried dark brown blood clot and then it was normal, since next morning I mean for the last 5 hours I am bleeding.is it normal menstruation? Generally it pains a lot during periods, this time its painless.

This is not a sign of pregnancy,
