I have been on the pill for 5 years but mess up every now and again!but iam living abroad and ran out of my pill and had unprotected sex maybe 6 days later  used the pull out method(we stopped after 5 min because i was scared):( after i panicked and took 4 pills and 12 hours later 3 more(as i had been told its like the morning after pill) and then continued my pack to the end and continued half another pack(to make my 21 days) then i stopped last sunday(24thjune) .on the tuesday i thought my period was starting because i got black and brown clots and the next day it was a more browny discharge with the one clot of red and the 3rd day it was back to clear! I had awful pains(like my period pains and still do but absolutly nothing! took a preg test on sunday morning and it was negative! I am living away from home and cant afford to go to the doctor! Is there a high chance iam pregnant?? or have i messed my insides up so much that my periods delayed? my last period started 21st may!!I know i made a lot of mistakes but trust me this week has been the worst waiting all day everyday for my period to come  thanks
