Trying to conceive baby number 4, previous three all conceived in first three months trying. Have regular cycles of 30 or 31 days, no more or less. Been using an ovulation kit and allegedly ovulated on day 18 which is my usual. Now day 35. No signs of a period, negative tests on a FRER and FMU.... but I think I ovulated 16 days ago... not massively stressed, or ill, so why else am I having a weirdly long luteal phase? And when will my bloody period start so we can get cracking on the next cycle?? Frustrated!
