Further to my question recently about the lack of menstrual periods for 2 months, the friend has decided she is coming to stay on the 1st Feb for a week before I go back to the UK.

As you said here, she can become fertile at any time, so I am wondering if there is a contraceptive pill she can take that has an (almost) immediate effect?

Add to that the lack of periods for 2 months, will that make any difference?

Morning after pills are obviously out of the question because they are a once only shot and not for daily usage..

Condoms neither of us like but will use if we have to.

Thanks for any advice

There are no contraceptive pills that work immediately, most require one or 2 controlled cycles before considered being effective.

At this point, she still have a hormone imbalance due to the effect of the progesterone with an unpredictable (and gradual) return to a normal balanced cycle; most physicians would usually recommend a waiting period with another contraceptive cover till she has her first period again. May be possible to start her on a hormone regime now to artificially create menstruation and then back to an appropriate oral contraceptive but this should be done with the guidance of a good gynaecologist.
