3weeks 4 days

ju

Cramps and back pain. Not severe but def feels like AF. Worried that I am starting a miscarriage again. I am 3 weeks and 4 days today. Going for my second HCG draw tomorrow. Have had 3 losses last year and so afraid I’m having another. Here are the progression of my tests. My line is getting darker. Anyone else have decent cramps and lower back pain and everything was ok??
