Since coming off the Pill in May, I've had some crazy long cycles - last one was 47 days!
Anyway, this month I tried one of the Clearblue digital ovulation kits as my friend gave it to me.
Two weeks into this cycle, I had high fertility on the test (never got to peak), EWCM, migraines and definitely noticed a heightened libido. So I assumed that was me ovulating, or my body at least thinking that's what was happening, which would have put me on an average 28 day cycle, although AF never arrived.
So then today (day 35 of cycle), the test showed high fertility again. It had dropped down to low in-between.
Long cycles, particularly if they are consistently long, can often be indicative of hormonal imbalances.
A "normal" cycle is a cycle length of between 21 and 35 days. Blood tests can be done to see what your hormone levels are like now. You initially need a day 2 test to check and compare your LH level against that of your FSH. These should be about the same; an imbalance of LH to FSH could be a possible indicator of a condition called polycystic ovaries.
If your periods are consistently irregular I would seek medical advice sooner rather than later. Blood tests as well can be done according to calendar days if the cycle is irregular as well.
These kits measure LH; what these kits assume is that there is one rise in LH every month and that such a rise is followed by ovulation. Both of these statements are simply not true. These kits are beset with problems and such kits should not be used with long cycles because they can give misleading false positive results. IIRC it states similar on the box.
Did you have irregular periods as a teenager as well?. If so periods are more likely to revert back to that irregular pattern. If you were given the pill because of this issue as well, the pill has basically masked the symptoms of the underlying problem.
Consistently long cycles should be investigated further to determine if there is a problem with the thyroid or if there is a condition like polycystic ovaries.
Yes - they were very irregular when I was young, and random too. Would last for weeks sometimes, then I'd go six months with nothing. So got put on the Pill at 15 and have been on it ever since (am now 32).
The three periods I've had since coming off the Pill have all lasted exactly five days - heavy for three, lighter for two - so they've been pretty 'text-book'.
