... steriods (prednisone) did not have sex during this time. The Thursday before I finished my pack I was sick during the night. Read the leaflet and it said treat it like a missed pill and so took another pill (my timing is 730 at night and I vomited at around 330am). I had unprotected sex Friday, Saturday and Sunday. I am now on my pill free week and am due to start new pack tomorrow but still no bleeding. What does this mean? Thanks and sorry I'm just very worried atm
