The "prueva de maternidad 7" event is gone

The 'prueba de maternidad 7' pregnancy event that I just started is gone. 
 I completely disappeared from the event window that started the day 'prueva de maternidad 7' started, and I can't start the event.
I haven't participated in this event in the past, so I don't have an event item.
Just in case, I started the 9th pregnancy quest with a married woman because I was wondering if I could get an event item if I did a normal 9th pregnancy quest, but it was a quest that gave me a pregnancy point, not an event item.
