Lines getting darker Bleeding heavy

bl

So I thought I was having a chemical but now I'm not so sure. I had heavy bleeding the day AF was due but I had already tested positive just faint I would have been 4 weeks. I bled heavy for a day and a half and then it went to a medium light period like flow and then stopped completely last night. I had a little bit of pink spotting about 2 hours ago that has now turned to a light Flow. It's been 4 days since the bleeding started I did have cramps and what looked like clots but very small. I did call the doctors and was told I was not able to be seen until September 29th I called again today and was told a nurse would call me back I am still waiting for that call back. I took a pregnancy test the day bleeding started yesterday and today that line has got progressively darker will post pictures.

Day it started^^
