My luteal phase is 11 days and i spot 2/3 days before my period starts. we've been trying to conceive for 14 cycles now. is this a problem?

Possibly...: It could represent 1. A Progesterone deficiency and perhaps blood levels may confirm a luteal phase defect 2. It may simply represent that you are ovulating a few days earlier than you think and this is withdrawal bleeding-lh testing or peri-ovulatory ultrasounds can help confirm this 3. Uterine polyps or fibroids and a sonogram-sonohysterogram can help identify any of these issues.
