So we are ttc again and I've always had a 28 day cycle and a cycle day 14 ovulation. I didn't get my cycle back till 9 months post partum this last pregnancy. I've been testing to find out my lh surge and my temperature change is cd 21 now, not 14 like it always has been. Then my period starts 7 days later. Is this why I'm not getting pregnant? Should I ask to see my OB to see what's going on or is it still possible to get pregnant? What has turned up for any of you? Any advice or help is greatly appreciated!

Just added info. I recently had all my thyroid labs done and those are all normal. My cycles are regular and not light or heavy. The only supplements I'm on are prenatal, vitamind and coq-10 which I was all on with the last conception.
