I got pregnant on bc... I had an alarm set on my watch and took it every day at the same time. I was using LoEstirn 24 Fe. The problem I ran into is that it's a low dosage and it eventually stopped my period alltogether. for 3 months I had no sign of anything and then I started feeling ill. For 2 of those 3 months I was pregnant. Never suspected. It has happened many times in my family and since it is full of nurses, I would like to think everyone was using it correctly, but you never know.
