How are contraceptives taken before IVF?

If the specialist considers that it is appropriate for the woman to take contraceptives before the IVF cycle, it is usual to start taking them at the beginning of the period (in the first three days of menstruation), once an ultrasound scan has been performed.

Contraceptive use usually lasts about two weeks, but this may vary depending on the individual situation. Once this period has elapsed, an ultrasound and/or hormone analysis will be carried out to check that the ovaries are resting. If this is the case, the woman will stop taking the contraceptive and, in about 5 days (known as the washout period), she will be able to start the ovarian stimulation treatment.

However, the guidelines established by the specialist must always be followed.
