Q

What are 9 areas of the gynaecological history that should be explored when starting contraception?

A
  1. Why they’re starting contraception and what they hope to get out of it
  2. Menstrual cycle: is it regular/prolonged, ⇒ some can help improve but can make it worse
  3. Irregular bleeding e.g. post-coital menstrual bleeding; can be a sign of STIs, if put coil in can cause pelvic inflammatory disease. Could also symbolise gyaencological cancer which could be worsened by some contraceptives
  4. Age: young (<16y), is she competent? As she gets older will increase risk of other medical problems, particularly with oestrogen containing contraceptives
  5. Any contraception already used, what they like/ don’t like
  6. Past pregnancies, particularly ectopic as some progesterone only can increase risk of ectopics
  7. Past pregnancies can also make putting coil in a bit easier (but not essential)
  8. What thinking about for future - want to get pregnant soon or never at all? Help decision
  9. Unprotected sex recently - STI risk
