On 21st January we had an intercourse( not a full one but penetrated twice and he had some protection on) . I took unwanted 72 pill the very same day after 2 hours. Everything was normal till 28th Jan when I had Browing discharge followed by bleeding the very next day.. however it was not very heavy ( I do not bleed heavily even during my periods as my haemoglobin level is low) and last for 1.5 days . I took a test with preganews the same day n it came negative. I am worried please help please.
