Hi please can you help on Friday the 24th February unfortunately the condom split, the day after I had bit of bleeding but just to be sure I took Levonelle in the Monday morning at 9 am, within the 72 hours, I already had bit of bleeding on that day but wanted to be extra safe. I bled for the whole week till Sunday the 5 th March. However I am experiencing signs of pregnany, it is now the 17th March, could I be pregnant or can side effects last that long, been having these symptoms for past week.Thank you
