robitussin

Does anyone know how/when I should take robitussin when I don't know when I will O? Any advice would be great thanks.

I usually took it 5 days leading up to when I thought I was going to O, it doesn't have to be precise, just the days leading up to when you think you will ovulate

I second what dloui says. Stick to the dosage on the bottle as well.

Problem is I really don't know when I'll O because of mc. I've heard it can be early or late :/

just start it after AF ends and carry on. IT's fine to take it earlier and later. not harmful in any way
