Pregnancy Info HOME

Hi I have had unprotected s_x a few times during the last month (I did not take my pill correctly)..I took my last pill on Saturday 22nd September and waited for my period (this usually starts 2-3 days after I have taken the last pill) however I did not start bleeding until Thursday 27 September. It was very very light and by Saturday morning I had stopped bleeding. I normally have a five day bleed heavy bleed so this was nothing like a normal period. I am however getting cramps. I have taken a pregnancy test today and it has come up negative. Im confused? Did I have a period and if so, why would I still be getting cramping feeling? I don’t normally have this. I also have lower back pain. The thing is when I was pregnant last year (I miscarried at 11 weeks) in the beginning I had cramping sensation and no period….so im not sure!!?? Could I be pregannt but it is just to early to tell on a test?
