Hi, I have taken unwanted 72 pill on 11 august after which I got my periods on 25th august and had a period length of 4 days (my last period date 2st august and my period length is of 5-6 days and a cycle of 25-30 days). In the 4 days of periods I experienced very less (as compared to usual) blood which was dark in colour and with it allot of clots. If we go with the trend my period is due between 23 September-26 September. Today when I am writing this is 24th September. I have been experiencing 1-2 red drops or sometimes pinkish liquid like spots max in whole day for last 4-5 days. And also I have taken 2 pregnancy test just to be sure with 2 different kits and both were negative and I have not had sex since the date I mentioned above on which I took the pill. What could it be? I am very worried. Please suggest me.
