I had so much hope this cycle

I’ve been dealing with late ovulation (day 22-23 of a 28 day cycle) and a very short luteal phase (7-8 days). This cycle my doctor changed my medication and put me on a low carb diet, and I ovulated CD 17 (yay!!). I usually try not to give myself hope, but I started to get so optimistic as I made it through 7, 8, and 9 dpo (even with that dramatic temp drop at 7 dpo). Alas, just woke up soaked in blood, 10 dpo. 😔 For anyone wondering, this is what a short luteal phase/luteal phase defect looks like...(note- since I woke up after only 1 hour of sleep, I have not temped yet tonight).
