Barfed up pill, how long until sex?

I had food poisoning over the weekend and singular barfed on Saturday. Obviously I barfed up the pill that I took that morning. I took my pill as normal yesterday (Sunday) and today (Monday). I lost the informational packet to my birth control (Estrostep FE) and when I jump to the Estrostep website and click on the link that would afford me the information I need, I return with a HTTP 404 error. So, I am trying to find out the following: How many days from Saturday, do I hold to take my pills back I can have sex w/o a condom again? I hear that it was 5 days, worth that it would take 5 days for everything to be locked and protected again. If this is true Thursday would be my fifth day and I can have condom free sex next to my b/f as of Friday? Someone else told me it was one and only 3 days required. Any solid answers? And links??

Does the morning after pill cause abortions?

if it be only one pill one time after you are ok to have sex again. If it be more then 2 pills consequently wait until the subsequent cycle.
