I've been off contraceptive for 2 years, but haven't fallen pregnant. I had a scan a few months ago but only just been given the results. It says about a collapsed Corpus Luteum, but surely if I've been TTC this wouldn't keep happening? Nothing else was spotted on the scan so next on the list is a blood test to rule out PCOS, but last tests came back normal. I experience very irregular cycles, from 17-39 days and my periods can go missing for months and are always very light lasting 2-3 days. I've been tracking my ovulation and had a peak on the 8th of December and another peak on the 19th, but as I'm getting negative pregnancy tests and no period I'm going with the 19th. Does anyone know why it could be taking so long, as doctors aren't worried because of my age (26) and I already have 2 children.
