Hi,I'm 15 and having frequent sex with my boyfriend,and most of the time around 4/5 times each weekend,we are protected as I'm taking the 21 day pill, accurately and safely,in this case,he doesn't pull out,but this month i was due my period 4 days ago and still haven't got it,I have had no sings of period cramps yet, it could just be late but I'm worried as I had sex yesterday,not especially rough but maybe a little,and I a couple hours later experienced light pinky watery spotting,only a very small amount,but I woke up today and there are no sings of a period,I do not want to get a pregnancy test or anything because I hate the idea,Me and my boyfriend would like to keep this between us and not tell parents because I'm too worried,are there any suggestions on what is happening,am I pregnant??
