Ok here is how it went.
My girlfreind is on YAZ. On yaz she has 24 active pill days. 7 eatch in week 1,2 and 3. then only 3 active pills in week 4 and the rest are 4 inactive pills.

About a week ago my gf missed 3 of the active pills in week 4. then she had her period. on monday feb 2st she started taking her pills again but she missed sundays. (sunday is when she started a new pack) she she took sundays AND mondays on monday.

Now today feb 6th we played around. i was in her ALITTLE without a condom. i did not fully go into her. i did that about 3 times then i just told her to finish me.

Now i know precum can get somebody preg so now i am worryied.

Should we go buy the EC pill? or are we safe???

On the yaz.com FAQ about missed pills it says nothing about missing the active pills in week 4. only weeks 1,2 and 3.
