I put one of those 'female' apps on my phone about 10 months ago. I mostly did it because my teenage DD has horrid PMT type mood swings and I wanted to track when her periods were happening. However, I have ended up using it for myself and the findings are quite interesting really....if you like that kind of thing, I guess...!! Anyway, I hadn't ever monitored my cycle before, not properly anyway. I would've guessed that my cycle is a bit longer than average and indeed it is about a 32 day cycle. And for the first 6 months or so I was very regular and on the days I was due to come on, I usually would. However, in the last three or four months everything has gone a bit bonkers and I'm not sure if it's anything to worry about. I've had two very long cycles - 41 days back in March (which at the time I put down to jet lag) and am currently on day 44 with no sign of coming on. I have had two periods in between too. I am definitely not pregnant. Is is just a weird female type 'blip' or is a crazy cycle that happens after apparent regularity cause for any concern...???
