Failed IVF (no transfer) on 14 March. Period started 24 March as I was told to expect, normally lasts 5-6 days, which it appeared to, but seem to have more light bleeding starting 1 April. Is this normal? Am going to have a few months 'rest' from IVF and try naturally - should I start testing for ovulation based on my 'first' or 'second' period?
