Good questions Nae I asked my group the same thing yesterday.

I started taking it a couple of weeks ago - and it has given me like morning sickness again. I even took a preg test this morning because it gave me a panic attack! So it was negative -so i am guessing it is the pill making me feel so sick.

I'm not sure what to do though - can you take the other pills when you are breastfeeding? I guess not - the hormones would be too strong.
Bit worrying.
