Hi my husband is due back from travelling for work in October before flying away again, and we are trying to conceive. The thing is, when he returns, I will have already passed my ovulation phase and will have to wait a couple more months before we can try again. Is there a way I can delay my period and therefore ovulation. I was thinking of taking either norestierone or evening primrose oil. I have a 24 day cycle and I am currently on day 2 ovulation. I am due for my period 29th September.
