After four months of charting following coming off the pill, I've figured out I have a much too short luteal phase. Eight days this cycle, eight the last, ten before that. (My cycles have been 24-29 days and show a clear temperature shift for ovulation.) Also, I tend to spot before my period begins, then I spot very dark brown for a few days after my period proper ends, which I've read probably indicates low progesterone. Well, crap.
I'm 34 and TTC child 1. I was on the pill for well over a decade and am worried I'm messed up. I asked my doctor if progesterone supplementation would be an option. She says that usually doesn't work and if I still can't conceive in a few more cycles, she will put me on Clomid. But I know Clomid can dry up your CM, I'm worried about ovarian hyperstimulation, and I don't think I could cope with multiples. I've also read mixed things about vitex agnus castus - some saying it can do the opposite of what you want it to. Womp womp. I don't want to faff around with it yet if I might end up worse than if I'd done nothing!
Has anybody here successfully lengthened their luteal phase? What actually worked for you? Any experiences with progesterone supplementation?
(I eat a healthy diet, normal BMI, take prenatal vitamins, and have almost completely cut out alcohol and caffeine, for what it's worth.)
