If I use the pill I would like some suggestions first about what to use and what I should avoid. I'm curious as to go on the pill that only gives you 4 periods a year, but I forgot the name. At the same time it sounds quite dangerous, so I would like some advice on it. Is it more expensive? Also, is it possible to use a brand that is less protective than the other, or do they all have to meat the same regulation? Lastly, what are the chances of getting pregnant using only the pill?
