I had my period around the 4th to the 8th jan..which will make it come again around the second 28-30 jan.. Because it happens 21 days!!.. I had sex on the 20th of Jan tuesdat and I took postinor2 the same day (one of the pill) I took the 2nd pill the next day however not exactly 12 hours after the first.. I took it about a hour or 2 late.. I started spotting(blood) too on the 28th which is 7 days after I had intercoutse/ 7 days since I took the first pill.. I am not sure though if its a sign that the pill was effective or its my period because my p was kinda due.. And I was reading up on something and bit said that sometimes women are pregnant and they mistake a pain the feel and blood flow for period so am not sure.. And concerned.. #worried.. Please reply maryann I need help with this.. Confused and not sure.. Going to take a ptest too.. Will it be effective will it show the correct info based on what I said..
