Spotting for the entire luteal phase

We are trying to convcieve and have been for 3 months or so. We have a healthy baby girl that we got pregnant with after one month of TTC. She is now 15 months.

I have been temping since January and can see a biphasic shift in my temps. The problem is that I spot around the time of ovulation for about three days and I start spotting about 3-5 days before my period comes. When I am spotting my temps still stay. Then I'll get the temp dip again when the red bleeding starts.

This cycle I have been spotting since I ovulated it had now been 8 days straight of spotting. What could be causing this? Could I be having a tubal pregnancy or be pregnant and have low progesterone?

My Dr. advised me to wait and see what happens. I am not happy with this as a solution to this problem. We would like to have another baby.

My luteal phase is always 14 days and my tempuratures are biphasic. Please help.

Some women will have a spot at the time of ovulation, this is normal from a brief drop in estrogen that occurs at ovulations and the LH surge. But you should not be bleeding the entire luteal phase. Agreeded your health and well being comes first, I would do a pregnancy test and see my Gyn about irregular bleeding rather than infertility,  a different thaught pattern, and it may just need time, but your Gyn should know, one may fix the other. An abnormal period now nad then is not abnormal, but that is not what I am reading.
Hope this helps,
