Hello, on the 19th of November I had sex where the condom broke, this was approximately 2 days after I had finished my period. The next day on the 20th I took the morning after pill levonelle. About a week and half after my period had ended and I'd taken levonelle I'd say 1st December, I received what I think is a withdrawal bleeding which was similar to a period but lighter and lasted a only a few days. I was due to be on my period 2 days ago and although I have had cramps and really bad back pain I have had no period which is really unusual for me. I am petrified I am pregnant. I did two tests at the doctors at 2 and half weeks and 3 weeks after sex but they came out negative.
