Hi!I had sex about a month or 20 days ago.I had a normal period, but now 4 days after my period ended when I whipped( 3-4 times) I saw blood.After that it stopped.My period is not so steady yet and usually lasts whole seven days.I caught a cold these days so I thought it my have affected me this way,or that some blood just didn't get out I don't know....I'm just really worried because it has never happened to me again.Could I be pregnant?
(to be more specific, I was on my period at 29th ofAugust - 5th of September, had sex at 16th-17th of September and got my last period from 28th September - 4th September.....and today 8th of September happened this incident)
