Any chance ?

My last AF was sept 1. I got a bfp on sept 25. It continued to get darker but on the 28th, the day AF would be due I had bleeding. I bled for 4 days. On October 2nd I had hcg tested which was 87. I've had no clots, no cramps. No bleeding since. I had a miscarriage in November 2016 and a stillbirth at around 23 weeks in may 2017. I haven't gotten my hcg levels repeated because my dr said it's another miscarriage. I took a pregnancy test today, middle of the day, it was a darker line immediately. Darker than control line. They won't check my progesterone levels.....
