I presume the prescription of primulute-N was to get a regular withdrawal - that's menses in case you haven't conceived in the cycle. I regret to differ, but Primulute-N is not a very good option while you are attempting pregnancy
. You better take micronized natural progestrones or Duphaston
in the same schedule. All these are progestogens (a type of hormones) but their finer qualities are varying. Primulut-N have higher male hormone like characters and have specific uses at specific situations but not while you are attempting pregnancy.
