I'm 44 (45 in Feb) and my last 4 cycles have been 20, 16, 33 and 16 days having previously been a regular 26-28 days since they came back after my daughter around 7 years ago. I'm pretty sure that this is peri and so in that regard I'm not concerned and I haven't had many other symptoms other than a couple of migraines and what I now think may have been night sweats/hot flushes and not just hot weather.
My question is whether or not I should see the GP? I read online that short cycles (fewer than 21 days) under the age of 45 should be investigated by a Dr.
