Has anybody experienced?

We have been trying almost two years with a miscarriage last year. Got the FAINTEST positive on Feb 7th. The day before it was stark white negative. I’m automatically high risk due to my autoimmune disease so I immediately called and they got me in for quant on the 10th and started me on progesterone and baby aspirin. My draw on the 10th was 57.5, 12th was 78.5 (which worried me), and 14th was 149.4, all noted on the chart. The bottom was today’s (3 in between was Saturday and Sunday), so clearly the line is wayyy darker! Is this a good progression? Especially with that one draw not being double? My dr should call me tomorrow (they were closed today) but I just want to know if anyone else has experienced a slow rise at first and everything be good

Thank you!
