Hello, I have such a question. two days ago my period ended with my friend, we have been trying for a baby for a year, but still nothing ... so we have booked a holiday, but unfortunately next month my period will be exactly my period. Is it possible to postpone menstruation? but won't it be that if I move it there won't be much chance of getting caught ?? or is it possible if I had my period now to call it again in about 3 weeks without getting it the way I should ?? would there be a catch in that invocation after 3 weeks? Thank you very much and if there is any more advice on how to get pregnant, I will be very happy :))
