Hey! Some people with a short cycle don’t have long enough for the lining to thicken for the embryo to implant. There’s medications that can put off ovulation to make sure the timing works. Have you reviewed anything With your doctor?
What is your cycle length like overall? Definitely sounds like your luteal phases are too short, I believe anything less than 9 days between ovulation and the start of your next menses is considered abnormal/too short.
I have really long cycles, not really short cycles. My cycle this time was 37 days with a 9 day luteal phase. The last cycle was 31 days with a 5 day luteal phase. The one before that was 39 days but I wasn't tracking ovulation so I don't know how long that luteal phase was. I haven't talked to my doctor about it yet because I've only had a few cycles since my baby was born, so I'm so worried all they're going to do is tell me it's because my cycle hasn't regulated yet.
Hey, I had something similar, please send me a message if you like :)
