What do I do?

I am 15 months postpartum and don't have a period. I have monthly spotting but not a period. I have had 3-4 chemical pregnancies within the past 7 months. I had one last month and now this month. I am not sure what to do I do not bleed after the tests go negative, but I do experience pain for a few days with some spotting. I test my Lh and basal temp everyday so I can try to see when I ovulate and my cycle. My doctor doesn't want to do anything about it and I am not sure what to do now..

**This is what I was receiving when positive it was bright pink, but now they are very light or negative.

**All my tests are positive within the time frame. I have been taking supplements so my pee is yellow and this test looks really yellow from it.

** I took the picture in a dark room and my phone also darkened the photo automatically. But in person there was an obvious pink line within the time frame
