I think I had a chemical pregnancy/super early miscarriage. Advice please.

This is going to be long and I'll preface it by saying I am seeing my doctor. Her soonest appt is Wednesday. And I just need advice and talk this out.

So last week I felt pregnant (AF due 4/9). On Monday I felt a pinching sensation and then mild cramping for a day or two. Nauseous, no appetite, fatigue, dizzy, sore boobs. None of these are PMS symptoms for me. There have been times that I thought I "could be pregnant" but this time I just felt like I knew. On Friday and Saturday I took preganacy tests. Both showed a vvvfl. Some of you on Glow agreed with me. A tweaked photo showed it too. On Sunday (AF expected date) I was waiting to test hoping it would be dark enough to tell my hubby. Tests were negative. No line at all. When I wiped there was brown blood. Very weird for first day of period. The majority of Sunday was just brown blood. Then it eventually just turned to dark red. All pregnancy symptoms stopped suddenly Sunday. When I woke up on Monday I had severe cramps (not typical) and my soft cup was overflowing. Yesterday (Monday) I had to change the cup 4 times and had to wear a pad! I normally only need to change once. Last night there were a lot of clots (not normal) and there was a lot of mucus like blood. I had considered that it could be a chemical pregnancy when I saw the atypical brown blood on Sunday but this just seemed to make it seem realer. It's just this horrible feeling but I don't even know if I'll have enough proof to know for sure. Am I totally wrong about this? Anyone experience something similar. I just want to cry but I'm staying as busy as I can.
