I ended my period on 26th June, I had unprotected sex on the 27th June, took postinol as a precaution on the 28th June. I started to bleed lightly (spotting, i guess) on 7th July and this lasted till 13th (my period length). But then i started bleeding (spotting) again two days after 13th (15th July) . It comes with a foul odour. I'm scared. Is this normal? Can i take some pills to make it stop? Help!!!
