I used it after having my bub. I found it to be very good. No bad symptoms at all.

You are meant to take it at the same time every day to make it work best. I read somewhere that around the time you take it is when it's at it's least effective so try not to take it at bedtime if that's when you are likely to DTD - do your pill taking earlier in the day.

I had already had my AF when I went on it so I can't answer the question about it bringing back your period. I do know though that some women don't get their AF at all whilst on the minipill. My cycle was exactly as it was before I got pregnant whilst I was on it.

I used it for around 8 months & did not fall pregnant during that time. I'm only off it now because I don't currently require contraception.
