Help please!!!!!

The past couple of cycles since I had a miscarriage, ovulation has been occurring late. I am now 3 DPO after having ovulated on CD 21. I have normal 29/30 day cycle. I used to ovulate around CD 16. My worry is that the luteal phase isn't long enough for implantation to occur. Has anyone else ever been through this and still gotten pregnant? Thanks!
