I don't know about how you should take SP or borage. When it comes to PM then there're different methods - taking it every day without breaks or taking it only from day 1 until your ovulation (or 1 day before ovulation). I don't know where 15 days came from, probably because most women ovulate in the middle of the cycle. But we all are different and some can have ovulation on day 8, for example. PM is the strongest phytoestrogen, so your method depends on your dose. Low doses are safe to take throughout the cycle. If you take high doses throughout the cycle I can make a qualified guess that you will either skip your period or get a big delay. You can expeiment and tell us about it. I also advise you to go through the archived forum and see how people were taking PM and what came out of it. Reading will take time but it's worth it.
