my partner and i have been trying for a baby for just over a month now. i was on cerezette for 4 years. we have had unprotected sex many times, however due to circumstances, i have decided to go back on the cerezette pill. my question is: i am worried if i go back on my pill and i am already pregnant? i have taken a pregnancy test today and it showed negitive, but it may not show up that i am pregnant yet. Are there any risks of me going back on my pill, or are there any time barriers i must work too? I hope you can help. Emma
