hi steph and welcome. A bit about me. I'm chele, have PCOS and just starting my journey through the UK health system.
This is my longest cycle ever. My first 6 cycles ttc were 28-34 days and this one is just coming to an end now I think. I went on BCP at 17 to control my weird cycles so for 11 years, my true problems were hidden.
Hope you get some answers soon and def start the process with ur doctors.
So a little update for you ladies...............
Ugh! I had cramps all day yesterday and then a strong one about 9=ish last night. Went to the toilet and it was a bit pink when i wiped. All cramping stopped at 10pm. Woke up at 7 for the toilet, temp still high - 36.65 and when I wiped it was a bit pink again, but there was a small red bit about the size of a 5p coin (sorry if tmi), I was half asleep so didnt analyse it too much. Then nothing else, but I put a pad on today. I've been to the toilet 3 times and each time there is nothing on the pad, but when I wipe it's orange/pinky staining on the toilet roll - so nothing gushing at this point. And still nothing on the pad.
So what's happening?

Normally when AF starts I get cramp for 30 minutes before, not 4 days and flow starts straight away. It's been nearly24 hrs now of nothing. Feeling more relaxed today but still convinced I am pregnant, so am thinking the stress in my head is making AF delay slightly.
What do you think?
And if I am now not pg, why? We did it so much, there must be another problem!!! I can't take that either............
Will monitor overnight and do an hpt tomorrow if it doesnt' start properly
